In this paper,a kind of boundary value problems for Volterra functional differential equation is studied.εx″(t)=f(t,x(t),(t),x(t-τ),x′(t),ε),t∈(0,1),x(t)=
In this paper the reaction-diffusion systems and the damped wave systems with nonlinear terms of gradient form are studied,and the conditions for making them to
