Title: Solutions to systems of partial differential equations with weighted self-reference and heredity Authors: Pham Ky Anh (Vietnam National Univ., Vietnam) Nguyen Thi Thanh Lan (Saigon Univ., Vietnam) Nguyen Minh Tuan (Vietnam National Univ., Vietnam) Abstract: This article studies the existence of solutions to systems of nonlinear integro-differential self-referred and heredity equations. We show the existence of a global solution and the uniqueness of a local solution to a system of integro-differential equations with given initial conditions. Submitted June 18, 2012.
