Abstract

This paper concerns iterated collocation methods for a class of nonlinear Volterra delay integral equations (VDIEs) with noncompact operators. Some properties of corresponding operators as well as existence, uniqueness and regularity of exact solution are discussed. Under a special graded meshes, the existence and uniqueness of collocation solutions are proved. Moreover, we present the global supper-convergence order. Finally, some numerical examples are given to verify the validity of the theoretical orders of convergence.
