Abstract

The purpose of this paper is to deal with the blow-up problems of the following p-Laplacian parabolic equations with nonlocal boundary conditions: h(u)t=|u|p2u+k1(t)f(u)in Ω×(0,t),|u|p2uν=k2(t)Ωg(u)dxon Ω×(0,t),u(x,0)=u0(x)0in Ω¯, where p>2, ΩRn (n2) is a bounded convex region, and the boundary Ω is smooth. With the help of differential inequality techniques and Sobolev inequalities, we prove that the blow-up does occur on some certain conditions of the data. In addition, we obtain upper bounds and lower bounds of the blow-up time in ΩRn (n2).
