On the Problem of Dissipative Perturbations of Nonexpansive Mappings

研究非扩张映象的耗散扰动问题· 并把所得结果应用于研究某些类型的非线性积分方程解的存在性

Some fixed point theorems for mappings of the type -A+T are established, where P is a cone in a Hilbert space,  A :P→2 P is an accretive mappings and  T :P→P is a nonexpansive mappings. In application, the results presented in the paper are used to study the existence problem of solutions for a class of nonlinear integral equations in L 2(Ω).
