In this paper,we study the solvability of several classes of differential inclusion-s.The main contents are as follows:In the first chapter,we introduce some basic conceptions and theorems about the study of differential inclusions.In the second chapter,we use the Leray-Schauder principle for set-valued maps to study the solvability of differential inclusionsandIn the third chapter,we use the Bohnenblust-Karlin's principle to study the existence of positive solution for a class of fourth-order differential inclusions... |
