报告摘要:
In this talk, we introduce mutation of cotorsion pairs in a Hom-finite Krull-Schmidt triangulated category. In a 2-Calabi-Yau triangulated category with cluster tilting objects, I give a complete classification of cotorsion pairs, which is helpful to describe how mutation behaves. A geometric interpretation is also given via rotations of paintings of a unpunctured marked surface. This is based on joint work with Bin Zhu.
