In this paper, the classical and weak derivatives with respect to spatial variab le of a class of hysteresis functional are discussed. Some conclusions about so
A delayed three-species ratio-dependent predator-prey food-chain model without dominating instantaneous negative feedback is investigated. It is shown that the
This note studies the existence of positive homoclinic orbits of the second orde r equation-u″+α(x)u=β(x)uq+γ(x)up, x∈R,where 1<q<p.Assume that the coeffici
By coincidence degree,the existence of solution to the boundary value problem of a generalized Liénard equation a(t)x"+F(x,x′)x′+g(x)=e(t),x(0)=x(2π),x′(0)=
The singularly perturbed elliptic equation boundary value problem with a curve o f turning point is considered. Using the method of multiple scales and the comp
In this paper,some conditions which assure the compactly supported refinable distributions supported on a self-affine tile to be Lebesgue-Stieltjes measures or
