HARVARD-MIT ALGEBRAIC GEOMETRY
March 3, 2020 3:00 pmIn a series of papers, Aluffi and Faber computed the degree of the GL3 orbit closure of an arbitrary plane curve. We attempt to generalize this to the equivariant setting...

February 28, 2020 3:30 pmWe give the first examples of codimension-1 knotting in the 4-sphere, i.e. there is a 3-ball B_1 with boundary the standard linear 2-sphere, which is not isotopic rel boundary to...

NUMBER THEORY
February 26, 2020 3:00 pmOne of the fundamental challenges in number theory is to understand the intricate way in which the additive and multiplicative structures in the integers intertwine. We will explore a dynamical...

RANDOM MATRIX
February 26, 2020 2:00 pmI will describe how certain recursive distributional equations can be solved by importing rigorous results on the convergence of approximation schemes for degenerate PDEs, from numerical analysis. This project is...

DIFFERENTIAL GEOMETRY
February 25, 2020 4:15 pmLet $M$ be a complete Ricci-flat manifold with Euclidean volume growth. A theorem of Colding-Minicozzi states that if a tangent cone at infinity of $M$ is smooth, then it is...

February 25, 2020 3:30 pmIn this work, we propose a systematical framework to construct Bell inequalities from stabilizers which are maximally violated by general stabilizer states. We show that the constructed Bell inequalities can...

February 25, 2020 3:00 pmIt is well known that, for pointed nodal curves, considering flat and proper families of pairs (X,D) leads to a proper moduli space. Still, while the notion of stable pairs...
