We introduce a sequence of numerical homotopy invariants ฯ i cat, i โ N, which are lower bounds for the Lusternik-Schnirelmann category of a topological space X. We characterize, with dimension restrictions, the behaviour of ฯ i cat with respect to a cell attachment by means of a Hopf invariant. Fur

In this paper we develop generalized Lyapunov and invariant set theorems for nonlinear dynamical systems wherein all regularity assumptions on the Lyapunov function and the system dynamics are removed. In particular, local and global stability theorems are given using lower semicontinuous Lyapunov f
