Infinite-Dimensional Problems,pings in some infinite-dimensional topological vector spaces. In this way, extensions of the Kakutani fixed point theorem are obtained for set-valued self-mappings of compact subsets in locally convex topological vector spaces (Ky Fan fixed point theorem), with their important special cases for sing

Difference Equations,ears. For first order equations, special attention is paid on their periodic solutions, by analogy with the case of ordinary differential equations. The method of lower and upper solutions is developed and presents some interesting distinct features from the corresponding differential case. Combined
