报告名称:Morse theory and moduli spaces of self-avoiding polygonal linkages
报告摘要:We show that a d-dimensional smooth manifold M is diffeomorphic to R^d if it admits a Lyapunov-Reeb function, i.e., a smooth map f: M → R that is proper, lower-bounded, and has a unique critical point. By constructing such functions, we prove that the moduli spaces of self-avoiding polygonal linkages and configurations are diffeomorphic to Euclidean spaces. This resolves the Refined Carpenter's Rule Problem and confirms a conjecture posed by Gonzalez and Sedano-Mendoza. Furthermore, we describe foliation structures of these moduli spaces via level sets of Lyapunov-Reeb functions and develop algorithms for related problems. This is a joint work with Te Ba.
