In this paper, we introduce the concept of dynamical distance on a nuclear configuration space. We partition the nuclear conguration space into disjoint classes. This classification coincides with the classical partitioning of molecular systems via the concept ofconjugacy of dynamical systems. It gives a quantitative criterion to distinguish differentmolecular structures. Manuscript profile

In this paper we introduce the concept of topological number for locally convextopological spaces and prove some of its properties. It gives some criterions to study locallyconvex topological spaces in a discrete approach. Manuscript profile
