报告摘要：
Associahedra (or Stasheff polytopes) were first introduced by Stasheff in his thesis to define the notion of A_n-spaces. Over time, these polytopes have continued to appear in various studies, including A_n-maps and moduli spaces, due to their rich combinatorial structures. In this talk, we will explore three additional models of these polytopes: Loday's cone construction, collapsed multiplihedra, and graph cubeahedra, and examine the combinatorial isomorphism between them.
