Maths HEP Lunchtime Seminars: Instantons on Gravitons

Presented by Sergey Cherkis (Dublin),

5 May 2006 00:00 in CM221

"N=4 Supersymmetric Gauge Theories in three space-time dimensions have Gravitational Instantons as their spaces of vacua. Typical examples of such spaces are Taub-NUT space and Atiyah-Hitchin moduli space of two monopoles. This relation leads us to construction of a large class of Gravitational Instantons as finite hyperkahler quotients. Using this realization we generalize the work of Kronheimer and Nakajima and construct Yang-Mills instantons on Gravitational Instantons."
