Title: Derivatives and Tangents In Increasing Abstraction Abstract: Derivatives? Heck yeah. Approximating more complex functions locally via linear approximations? Radical. Understanding tangent spaces on manifolds? Tubular. But what if you […]
Title: 2-torsion in class groups of odd degree extensions Abstract: A major question in number theory is to determine the distribution of the class group in families of number fields. […]
Title: Twisted graded categoriesAbstract: Given a presentably symmetric monoidal ∞-category C and a commutative monoid M, we introduce and classify twisted graded categories, which generalize the Day convolution structure on Fun(M, […]
Title: Rigidity of ancient ovals in mean curvature flow. Abstract: We will discuss the classification of ancient noncollapsed flows as singularity models of mean curvature flow. In particular, I will […]
Title: Higher Period Integrals and Derivatives of L-functions. Abstract: We will describe the local-to-global construction of Kolyvagin systems in the preprint https://arxiv.org/abs/2504.00275 by Liu and Wang.
Title: Higher Period Integrals and Derivatives of L-functions. Abstract: We will explain how the construction of Kolyvagin systems in the preprint https://arxiv.org/abs/2504.00275 by Liu and Wang specializes, unconditionally, to previous […]
Title: Elliptic curves, Galois theory, and Mazur’s “Program B”.Abstract: The “N-torsion field Q(E)” of an elliptic curve E over the rationals is the field obtained by adjoining the coordinates of […]
