Zeta functions of alternate mirror Calabi-Yau families
TL;DR: In this paper, it was shown that if two Calabi-Yau invertible pencils have the same dual weights, then they share a common factor in their zeta functions.
Symplectic Automorphisms and the Picard Group of a K3 Surface
TL;DR: In this article, the rank and discriminant of the Picard group on a K3 surface X has been computed using moduli spaces of K3 surfaces with symplectic G-action.

Classifications of elliptic fibrations of a singular K3 surface
Marie José Bertin,Alice Garbagnati,Ruthi Hortsch,Odile Lecacheux,Makiko Mase,Cecília Salgado,Ursula Whitcher +6 more
TL;DR: In this article, the authors classify, up to automorphisms, the elliptic fibrations on the singular K3 surface $X$ whose transcendental lattice is isometric to Θ( √ 6\rangle\oplus \langle 2/rangle).

Short Tops and Semistable Degenerations
Ryan Davis,Charles F. Doran,Adam Gewiss,Andrey Y. Novoseltsev,Dmitri Skjorshammer,Alexa Syryczuk,Ursula Whitcher +6 more
TL;DR: The method is constructive: given a fixed reflexive polytope that will lie on the boundary of the top, this work describes an algorithm for constructing tops that yields semistable degenerations of the corresponding hypersurfaces.

Women's Representation in Mathematics Subfields: Evidence from the arXiv
Abra Brisbin,Ursula Whitcher +1 more
TL;DR: Men are under-represented as authors of mathematics papers on the arXiv as mentioned in this paper, even in comparison to the proportion of women who hold full-time positions in mathematics departments.
