# Topology, Algebraic Geometry, and Dynamics Seminar (TADS): The Rarita-Schwinger Operator, from Index Theory to Gauge Theory

Nov 17, 2023, 1:30 - 2:30 PM

**Speaker:** Ahmad R.H.S. Sadegh, Northeastern University

**Title:** The Rarita-Schwinger Operator, from Index Theory to Gauge Theory

**Abstract:**** **The bundle of 3/2-spinors is the subbundle of spinors twisted with the tangent bundle, obtained as the kernel of Clifford action. The contraction of the twisted Dirac operator to the bundle of 3/2-spinors is called the Rarita-Schwinger operator. This operator is not a Dirac-type operator but shares many properties with Dirac operators, such as having a Weitzenbock-type formula. We discuss some index theoretic and gauge theoretic aspects of this operator.

**Time:** Friday, November 17, 1:30pm – 2:30pm

**Place:** Exploratory Hall, room L111
