摘  要: In this talk, we present the following result: the systolic volume of a closed aspherical 3-manifold is bounded below in terms of complexity. Systolic volume is the optimal constant in a systolic inequality. Gromov showed that the systolic volume is related to some topological invariants measuring complicatedness. In dimension three, complexity defined in terms of triangulation is a natural tool to evaluate topological complicatedness. Both systolic volume and complexity are important topological invariants, but the understanding of them is very poor. The work introduced in this talk is a new development to the research of these two invariants.
