Lie Algebraic Saddles of the IKKT Matrix Model

This semi-informal seminar will feature about one hour of prepared presentation, with ample time reserved for questions and discussion.

Abstract:
The IKKT matrix model as a promising non-perturbative formulation of type IIB superstring theory has been studied extensively over the past few decades both numerically and analytically. However, due to the nonlinear nature of its equations of motion, the saddle structure of the IKKT matrix model remains underexplored. In this talk, we consider the matrix degrees of freedom to be representations of finite dimensional Lie algebra, and discuss how to construct saddles accordingly. As a physical example, we apply dequantization map to discuss how curved spacetime can emerge from these saddles.
