TL;DR: In geometric function theory, generalized elliptic integrals and functions arise from the Schwarz-Christoffel transformation of the upper half-plane onto a parallelogram and are naturally related to Gaussian hypergeometric functions.
Abstract: In geometric function theory, generalized elliptic integrals and functions arise ?from the Schwarz-Christoffel transformation of the upper half-plane onto a parallelogram and are naturally related to Gaussian hypergeometric functions. Certain combinations of these integrals also occur in analytic number theory in the study of Ramanujan’s modular equations and approximations to π. The authors study the monotoneity and convexity properties of these quantities and obtain sharp inequalities for them.
TL;DR: In this article, it was shown that λ alg E = λ anal E = 0 and λ anal E = ∞, respectively, for the case of modular elliptic curves with multiplicative reduction at p. The main conjecture for E over Zp-extension Q ∞ of Q is proved.
Abstract: Suppose that E is an elliptic curve defined over Q, and that p is a prime where E has good ordinary reduction. Under the assumption that E is modular, one can define nonnegative integers λ E , μ alg E , λ anal E , and μ anal E . The “algebraic” Iwasawa invariants λ alg E and μ E are defined in terms of the structure of the p-primary subgroup SelE(Q∞)p of the Selmer group for E over the cyclotomic Zp-extension Q∞ of Q. The definition of the “analytic” invariants μ E and λ anal E is in terms of the p-adic L-function for E constructed by Mazur and Swinnerton-Dyer [MSD74]. We will recall these definitions below. Our purpose in this article is to prove in certain cases that μ E = μ anal E = 0 and that λ alg E = λ anal E . These equalities, together with a deep theorem of Kato, imply the main conjecture for E over Q∞. In this introduction, we will discuss the nature of our results and give an outline of the proofs for the case of modular elliptic curves. We want to point out, however, that the theorems proven in the text apply to modular forms, as well as to elliptic curves with multiplicative reduction at p. We will not attempt to state the most general versions here. If K is any algebraic extension of Q, then the Selmer group for E over K is a certain subgroup of H(GK , E(Q)tors), where GK = Gal (Q/K). The Selmer group fits into an exact sequence 0 → E(K)⊗Q/Z → SelE(K) → XE(K)

TL;DR: In this article, the Eichler-Zagier isomorphism between Jacobi forms and modular forms of half-integral weight was generalized to higher levels and the explicit Waldspurger theorem was obtained for Jacobi cusp newforms.
Abstract: In this paper, we set up Shimura and Shintani correspondences between Jacobi forms and modular forms of integral weight for arbitrary level and character, and generalize the Eichler-Zagier isomorphism between Jacobi forms and modular forms of half-integral weight to higher levels. Using this together with the known results, we get a strong multiplicity 1 theorem in certain cases for both Jacobi cusp newforms and half-integral weight cusp newforms. As a consequence, we get, among other results, the explicit Waldspurger theorem.
TL;DR: The L-series of two Calabi-Yau three-folds of the middle cohomology has dimension 2, and the Mellin transform is given by a modular form of weight four.
TL;DR: In this paper, the universal covering of the moduli space of complex structures by non-commutative spaces is proposed, which are described by certain categories of sheaves with connections which are flat along foliations.
Abstract: We suggest to compactify the universal covering of the moduli space of complex structures by non-commutative spaces. The latter are described by certain categories of sheaves with connections which are flat along foliations. In the case of abelian varieties this approach gives quantum tori as a non-commutative boundary of the moduli space. Relations to mirror symmetry, modular forms and deformation theory are discussed.
TL;DR: In this article, the authors studied graded traces of vectors in free bosonic vertex operators and lattice vertex operator algebras, and they showed that trace functions in these two theories always have the shape f(q)/\eta(q)^d where f(qs) is quasi-modular in the case of d free bosons, and modular (i.e., a sum of holomorphic modular forms of various weights) in theory based on a lattice L of rank d.
Abstract: We study graded traces of vectors in free bosonic vertex operator algebras and lattice vertex operator algebras. We show in particular that trace functions in these two theories always have the shape f(q)/\eta(q)^d where f(q) is quasi-modular in the case of d free bosons, and modular (i.e., a sum of holomorphic modular forms of various weights) in the case of theories based on a lattice L of rank d. We also show how spherical harmonic polynomials with respect to L are related to primary fields in lattice theories.
TL;DR: In this article, the authors determine the space of 1-point correlation functions associated with the Moonshine module, which are precisely those modular forms of non-negative integral weight which are holomorphic in the upper half plane, have a pole of order at most 1 at infinity, and whose Fourier expansion has constant 0.
Abstract: We determine the space of 1-point correlation functions associated with the Moonshine module: they are precisely those modular forms of non-negative integral weight which are holomorphic in the upper half plane, have a pole of order at most 1 at infinity, and whose Fourier expansion has constant 0. There are Monster-equivariant analogues in which one naturally associates to each element in the Monster a modular form of fixed weight k, the case k=0 corresponding to the original ``Moonshine'' of Conway and Norton.
TL;DR: In this article, it was shown that the Siegel modular functions satisfy a Gauss-Manin connection, whose monodromy groups are well-known, and that the partial differential equations they satisfy are governed by Gaussmanin connections.
Abstract: It is a classical fact that the elliptic modular functions satisfies an algebraic differential equation of order 3, and none of lower order. We show how this generalizes to Siegel modular functions of arbitrary degree. The key idea is that the partial differential equations they satisfy are governed by Gauss--Manin connections, whose monodromy groups are well-known. Modular theta functions provide a concrete interpretation of our result, and we study their differential properties in detail in the case of degree 2.
TL;DR: In this paper, the p-adic valuation of the eigenvalue of Tp is defined as the slope of a modular form of weight k, level N, and trivial character which is an eigenform for the pth Hecke operator Tp.
Abstract: Fix a prime number p and choose, once and for all, an embedding of the algebraic closure of Q into Qp. Let k and N be integers, and suppose N is not divisible by p. If f is a modular form of weight k, level N, and trivial character which is an eigenform for the p-th Hecke operator Tp, we define the slope of f to be the p-adic valuation of the eigenvalue of Tp. This paper reports on computations that suggest that there is quite a lot of structure to the set of slopes for eigenforms of varying weight k. In particular, we find that the slopes are often smaller than expected, that they are almost always integers, that there is evidence of a connection between fractional slopes and slopes which are "bigger than usual", and that there are some hints of a connection to the theory of theta-cycles.

TL;DR: In this paper, the Ramanujan property is studied for cubical complexes which are uniformized by an ordered product of regular trees, and explicit arithmetic examples using quaternion algebras over totally real fields are constructed.
Abstract: This paper considers a higher-dimensional generalization of the notion of Ramanujan graphs, defined by Lubotzky, Phillips, and Sarnak. Specifically the Ramanujan property is studied for cubical complexes which are uniformized by an ordered product of regular trees. We construct explicit arithmetic examples using quaternion algebras over totally real fields. Here we reduce the Ramanujan property to special cases of the Ramanujan-Petersson conjecture for holomorphic Hilbert modular forms, many of which are known.
TL;DR: In this paper, the authors constructed several new elliptic integrals of this type using modular identities associated with certain "Hauptmoduls" and proved these identities using only results found in Ramanujan's notebooks.
Abstract: On pages 51–53 of his lost notebook, S. Ramanujan expressed several integrals of products of Dedekind eta-functions in terms of incomplete elliptic integrals of the first kind. In this paper, we prove these identities using only results found in Ramanujan’s notebooks. We then construct several new elliptic integrals of this type using modular identities associated with certain “Hauptmoduls.”
TL;DR: Ramanujan used modular equations to evaluate class invariants, certain q-continued fractions, and certain quotients and products of theta functions and eta functions as mentioned in this paper.
Abstract: Ramanujan recorded several hundred modular equations in his three notebooks [7]; no other mathematician has ever discovered nearly so many. Complete proofs for all the modular equations in Ramanujan’s three notebooks can be found in Berndt’s books [1]–[3]. In particular, Chapters 19–21 in Ramanujan’s second notebook are almost exclusively devoted to modular equations. Ramanujan used modular equations to evaluate class invariants, certain q-continued fractions including the Rogers-Ramanujan continued fraction, theta-functions, and certain other quotients and products of theta-functions and eta-functions [3].
TL;DR: In this paper, it was shown that under certain assumptions, a modular form can be lifted to yield a new form on a unitary group of rank 3 with the same modular Galois representation.
Abstract: A well-known theorem of Ken Ribet asserts that, under certain assumptions, a modular form (mod )o nΓ0(N) can be "lifted" to yield a newform on Γ0(N ) with the same modular Galois representation. For further progress in the modular theory of automorphic forms one will need to understand this phenomenon for automorphic forms on reductive groups other than GL(2). In this paper we prove such a result for the unitary group of rank 3, under suitable assumptions. The proof relies on the modular representation theory of p-adic reductive groups. 1. Introduction. Suppose N 1 is an integer and Γ0(N) SL (2, )i s the usual Hecke subgroup; S2(Γ0(N)) denotes the space of cusp forms of weight 2. Let f S2(Γ0(N)) be a new form (with trivial Nebentypus) that is an eigen- form for all the Hecke operators T( p), with Fourier expansion
TL;DR: In this paper, the authors provide a new proof of Rademacher's celebrated exact formula for the partition function, along with a simple treatment of an integral which is ubiquitous in the theory of nonanalytic automorphic forms.

TL;DR: In this article, the weight-monodromy conjecture for l-adic representation associated to modular forms has been shown to hold for Hilbert modular forms, and a correct argument on an ambiguous point in the proof has been given.
Abstract: The purpose of this short paper is to state the weight-monodromy conjecture for l-adic representation associated to modular forms, which is implicitly proved in the paper [10], and to give a correct argument on an ambiguous point in the proof in it. The monodromy-weight conjecture is mentioned in [8, (3.2)]. We will prove the corresponding property for Hilbert modular forms in a forthcoming paper [11].
TL;DR: In this article, the authors studied the cohomology groups of coherent sheaves on a Griffiths-Schmid variety associated with an anisotropic Q-from of the unitary group SU(2,1).
Abstract: Our aim is to study the cohomology groups of some coherent sheaves on a Griffiths–Schmid variety associated with an anisotropic Q-from of the unitary group SU(2,1). We define some transforms relating this cohomology to the coherent cohomology groups of some sheaves defined on certain threefolds, which are fibered in projective lines over Picard modular surfaces. In particular, we give a complete and explicit description, in terms of classical Picard modular forms, of the holomorphic (resp. anti-holomorphic) part of the 1-cohomology of the Griffiths-Schmid variety. From this, it results an explicit generating system for the part of the 2–cohomology which correspond to those automorphic representations whose archimedean component is a degenerate limit of discrete series.
