This page hosts information on Juan Orduz's talk "What is … a Dirac operator?" at the "What is …?" seminar. The talk will take place on Friday, June 15, 4:00pm at the BMS Lounge in TU, MA 212.
The main idea of this talk is to introduce the notion of a Dirac Operator from the physical problem of finding the quantum equation for a relativistic electron. After that we will explore how these ideas can be generalized in order to find a general geometric setting for these operators and how they can be used to construct a bridge between analysis and topology via index theorems.
