Positive solutions for Neumann boundary value problems of nonlinear second-order integro-differential equations in ordered Banach spaces
نویسندگان
چکیده
in an ordered Banach space E with positive cone K, where M >0 is a constant, f : [0, 1] × K × K ® K is continuous, S : C([0, 1], K) ® C([0, 1], K) is a Fredholm integral operator with positive kernel. Under more general order conditions and measure of noncompactness conditions on the nonlinear term f, criteria on existence of positive solutions are obtained. The argument is based on the fixed point index theory of condensing mapping in cones. Mathematics Subject Classification (2000): 34B15; 34G20.

متن کاملGlobal solutions for second order impulsive integro-differential equations in Banach spaces
This paper regards initial value problem for second order impulsive integro-differential equations as some nonlinear vector system. By means of the Mönch′s fixed point theorem, some existence theorems of solutions of the initial value problem are established. The results are newer than all of the previous ones because of the more general form compactness-type condition and the weaker restrictio...
