Maths HEP Lunchtime Seminars: Topological Strings and Special holonomy
9 December 2005 13:00 in CM221
"The usual topological strings are constructed on six dimensional Calabi-Yau manifolds. We will describe the construction of new topological string theories on manifolds of special holonomy: seven dimensional G_2, and eight dimensional Spin(7) manifolds. These theories give a new perspective on the geometry of special holonomy manifolds."
