Title：

TT Deformations of Yang-Mills Theories

Abstract:

In this talk, I will discuss classical deformations of non-Abelian gauge theories which are driven by functions of the energy-momentum tensor, and which are inspired by Zamolodchikov's TTbar operator in two dimensions. Although finding the full solutions to these flow equations is difficult, one can nonetheless make progress by restricting to special field configurations such as instantons and monopoles. I will also describe a modification of these stress tensor flows, called the "symmetrized single trace TT deformation", which -- when applied to a Yang-Mills seed theory -- produces Tseytlin's symmetrized trace prescription for non-Abelian Born-Infeld theory.

Symplectically Flat Bundles and Yang-Mills Type of Functionals
AbstractIn analogous to flat bundle and holomorphic bundle, we introduce a special type of vector bundle over symplectic manifolds, which is called symplectically flat. The corresponding connection is called a symplectically flat connection and its curvature is proportional to the symplectic form. Considering that flat connections are the zero points of Yang-Mills functional, we construct two s...
