讲座简介:Let A be a homologically smooth graded gentle algebra with Koszul duality A! and K the Koszul functor, which is a triangle equivalence from pvd(A) to per(A!) We show that in the geometric mode K can be realized as the (anti-clockwise) half rotation. As a byproduct, we prove an intersection formula. This is a joint work with Qiu Yu and Zhou Yu.
