Lifts of projective congruence groups, II
TL;DR: It is shown that noncongruence subgroups of SL2(Z) projectively equivalent to congruence sub groups are ubiquitous and developed algorithms that construct all subgroups projectively equiv- alent to a given congruences subgroup and decide which of them are congruent.

On congruences mod pm between eigenforms and their attached Galois representations
TL;DR: In this article, the authors considered the problem of deciding whether f 1 and f 2 have the same eigenvalues mod p m (where p is a fixed prime of K over p) for Hecke operators T l at all primes l ∤ N p.

Lifts of projective congruence groups
TL;DR: In this article, it was shown that noncongruence subgroups of SL2(Z) projectively equivalent to congruence subgroup are ubiquitous and can be found in many cases also for 0(N).

A Note on a Theorem of A. Granville and K. Ono
TL;DR: Granville and Ono as discussed by the authors proved that every natural number has a t-core partition for t ∈ N, t ⩾4 if and only if t ≤ 2.

Quadratic Twists of Rigid Calabi–Yau Threefolds Over ℚ
TL;DR: In this article, the notion of quadratic twisting of a rigid Calabi-Yau threefold is defined and the question of whether it admits quadratics is investigated.
