#### Lie groupoids and algebroids in geometric mechanics

###### Ari Stern (Washington University St. Louis)

Abstract: Geometric mechanics has deep historical connections with symplectic and Poisson geometry, as well as with the geometry of Lie groups and algebras. More recently, the theory of Lie groupoids and algebroids has led to important generalizations and increased understanding of earlier work, particularly relating to symmetries, reduction, and discretization. In this talk, I will provide an overview of this topic and share some recent results.

#### An introduction to 0-dimensional schemes on a smooth quadric

###### Eliana Duarte (UIUC Math)

Abstract: In this talk we will study the geometry of 0-dimensional schemes on a smooth quadric by looking at its bi-graded Hilbert function and free resolution. I will talk about the motivation to study such objects and give several friendly examples.

#### Many C*-norms

###### Mathew Wiersma (Waterloo)

Abstract: We continue our discussion from last time
