Characterization for the convergence of Krasnoselskij iteration for non-Lipschitzian operators.
2000 Mathematics Subject Classification: 90C26, 90C20, 49J52, 47H05, 47J20.In this paper we obtain some simple characterizations of the solution sets of a pseudoconvex program and a variational inequality. Similar characterizations of the solution set of a quasiconvex quadratic program are derived. Applications of these characterizations are given.
In the present paper, the existence of a weak time-periodic solution to the nonlinear telegraph equation with the Dirichlet boundary conditions is proved. No “smallness” assumptions are made concerning the function . The main idea of the proof relies on the compensated compactness theory.
