Title: Injectivity Theorem for Generalised Pairs on Surfaces

Abstract:

In this talk, we study the question proposed by Caucher Birkar about injectivity theorem on cohomologies of generalised pairs. By applying the techniques from complex analytic geometry, we show that the injectivity theorem holds unconditionally for generalised Kawamata log terminal (g-klt) generalised pairs on projective surfaces.
