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.
