"(Non-)Geometry of SCFTs"

In this talk I will discuss a number of examples where IR fixed points of a class of supersymmetric field theories are characterized by (non-)geometric data. Our examples include 4d N=1,2 SCFTs and 3d N=2 SCFTs, with or without Lagrangian. The data characterizing IR fixed points includes the geometry of 2-manifolds and 3-manifolds, cells of the positive Grassmannian, and combinatorics of quiver mutations.
