Abstract

The method of generalized quasilinearization [4] is applied to study semilinear parabolic equation utLu=f(t,x,u) with nonlocal boundary conditions u(t,x)=Ωϕ(x,y)u(t,y)dy in this paper. The convexity of f in u is relaxed by requiring f(t,x,u)+Mu2 to be convex for some M>0. The quadratic convergence of monotone sequence is obtained.
