Abstract
In this paper, we study the following operator equation:
p∈Ax+Cxp∈Ax+Cx
Turn MathJax on
in a Banach space XX, where A:D(A)⊆X→2XA:D(A)⊆X→2X is an accretive mapping, C:D(C)⊆X→XC:D(C)⊆X→X is a nonlinear mapping and p∈Xp∈X. Various existence results of solutions of nonlinear operator equations in Banach spaces are obtained under a countably condensing type condition.
