Outline 课程安排	The main topic of these three lectures is on recent developments in solvable irrelevant deformations of 2d quantum field theories. In the first lecture, I will introduce the T-Tbar deformation of 2d QFT. Special emphasis will be put on the deformed Lagrangian and the exact solvability of the spectrum. In the second lecture, I will focus on the torus partition sum of the T-Tbar/J-Tbar deformed CFTs and modular invariance/covariance. In the third lecture, I will present different perspectives on the T-Tbar deformation including the relations to random geometry, Jackiw-Teitelbolm gravity and holography.
