It is shown that any fixed point of a Lipschitzian,strictly pseudocontractive muping T on a closed convex subset K of a Banach space X may be approximated by Is
By means of continuation theorem of the coincidence degree theory, sufficient conditions are obtained for the existence of periodic solutions of a kind of third
In this paper the nonnegative classical solutions of a parabolic system with nonlinear boundary conditions are discussed. The existence and uniqueness of a nonn
The existence of positive solutions for second order m-point boundary value problem X^''-q(t)f(x,x')x'=0,x(0)=∑↑mi=zbix(ξ),x'(1)=ax'(
In this paper the perturbed neutral differential equation with positive and negative coefficients d/dt[x(t)-C(t)x(t-r)]+p(t)x(t-x)-Q(t)x(t-δ)=f(t,x(t)),t≥t0is
