摘要：Exchange graphs originally appeared in cluster theory. Subsequently, it has been established that exchange graphs also appear in the context of support tau‑tilting modules over finite‑dimensional algebras, as well as silting objects in derived categories, among others. In this talk, we give a concise introduction to cluster algebras and then focus on the question of shortest mutation paths. If time permits, we will discuss the support tau-tilting graphs of finite-dimensional algebras.
