In this paper, we establish sufficient conditions for the controllability of nonlinear neutral evolution equations with nonlocal conditions. The result is obtained by using Krasnoselski-Schaefer type fixed point theorem.
By using Banach contraction principle, we obtain the global results (with respect to ||A||≠1) on the sufficient conditions for the existence of nonoscillatory solutions to a system of nonlinear neutral delay di...By using Banach contraction principle, we obtain the global results (with respect to ||A||≠1) on the sufficient conditions for the existence of nonoscillatory solutions to a system of nonlinear neutral delay difference equations with matrix coefficients.展开更多
