报告摘要:

For a triangulated category C with a cluster tilting subcategory T which contains infinitely many indecomposable objects, the notion of weak T[1]-cluster tilting subcategories of C is introduced. We use them to study the τ-tilting theory in the module category over T. Inspired by the work of Iyama-Jørgensen-Yang, we introduce the notion of τ-tilting subcategories of mod T, and show that there exists a bijection between weak T[1]-cluster tilting subcategories of C and support τ-tilting subcategories of mod T. Moreover, we describe the subcategories of mod T which correspond to cluster tilting subcategories of C. This generalizes and improves results by Adachi-Iyama-Reiten, Beligiannis, and Yang-Zhu.
