摘要
In this paper, the simultaneous existence of positive, negative and sign-changing periodic solutions for a class of integral equations of the form phi(x) = integral([x,) (x+omega]boolean AND Omega) K(x, y)f(y, phi(y - tau)))dy, x is an element of Omega, is considered. where Omega is a closed subset of R-N with a periodic structure. Our main result is different from most existing results since they provide three constant sign periodic solutions only. (C) 2010 Elsevier B.V. All rights reserved.
