A pedagogical review on solvable irrelevant deformations of 2d quantum field theory

Understand

This is a pedagogical review on $\mathrm{T}\overline{\mathrm{T}}$ deformation of two dimensional quantum field theories.

• It is based on three lectures which the author gave at ITP-CAS in December 2018.
• This review consists of four parts.
• The first part is a general introduction to $\mathrm{T}\overline{\mathrm{T}}$ deformation.
