Title: Special Positions of Shapes in Four-Dimensional Space
Abstract: I will begin by convincing you that four-dimensional space is more familiar than it might first appear. Then, I will introduce ways in which mathematicians study objects in 4-space. Each visualization method comes with its own advantages and limitations, as well as a natural measure of complexity that captures how "knotted" a shape can be. Drawing from my work on several projects, I will explain how these complexity measures connect to other areas of mathematics. For example, placing surfaces in what we call a rainbow position reveals connections to symplectic geometry. |

Title: Schubert varieties are splinters
Abstract: Schubert varieties are among the most well-studied singular algebraic varieties, and they have numerous applications in combinatorics and representation theory. In positive characteristic, Schubert varieties are known to be Frobenius split by the work of Mehta and Ramanathan. More recently, Bhatt showed that the full flag variety for GL_n is a derived splinter by entirely different methods. In this talk, we explain these concepts and we show how to generalize Bhatt's result to all Schubert varieties. Our methods apply equally well to affine Schubert varieties, which are of interest in number theory. This is joint work with Joao Lourenco. |
