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 […]
Title: Finding the walls in GIT.Abstract: Geometric Invariant Theory (GIT) can be used to construct familiar varieties, including many toric varieties, as well as flag varieties or more generally moduli of […]
Title: Ramification in geometric Langlands and representation theory.Abstract: Some celebrated recent work of Arinkin–Beraldo–Campbell–Chen–Faergeman–Gaitsgory–Lin–Raskin–Rozenblyum settles the unramified geometric Langlands conjecture, which is a certain equivalence of categories related to closed […]
