摘      要：This is a pedagogical review on TT^(-)deformation of two dimensional quantum field *** is based on three lectures which the author gave at ITP-CAS in December *** review consists of four *** first part is a general introduction to TT^(-)*** emphasises are put on the deformed classical Lagrangian and the exact solvability of the *** second part focuses on the torus partition sum of the TT^(-)/JT^(-)deformed conformal field theories and modular invariance/*** the third part,different perspectives of TT^(-)deformation are presented,including its relation to random geometry,2D topological gravity and *** summarize more recent developments until January 2021 in the last part.
