Invertible Functorial Field Theory for Symmetry Breaking and Interactions in Quantum Field Theory
(Massachusetts Institute of Technology, 2025-05)We apply invertible field theories to study two questions in quantum field theory. Specifically, we study reflection-positive fully-extended invertible field theories on manifolds with twisted spin structures, which are ... -
Computational Tradeoffs and Symmetry in Polynomial Nonnegativity
(Massachusetts Institute of Technology, 2025-05)Understanding when a polynomial is nonnegative on a region is a fundamental problem in applied mathematics. Although exact conditions for nonnegativity are computationally intractable, there has been a surge of recent work ... -
Affine Springer Fibers and the Kazhdan-Lusztig Map
(Massachusetts Institute of Technology, 2025-05)Let G be a connected reductive group with Lie algebra g and Weyl group W. Let P ⊂ G((t)) be a parahoric subgroup with Levi quotient Gₚ. Using the topology of Lie P, Kazhdan and Lusztig define a map from nilpotent orbits ...
