摘要
In this paper we study the blow-up behavior for a class of semilinear parabolic variational inequalities;whereK = {u ∈L<sup>2</sup>(0,T;H<sub>0</sub><sup>1</sup>(Ω))|u(x,t)≥ψ(x) a. e. (x,t) ∈Ω×(0,T), u(x,0) = (x)},andis a uniformly elliptic operator.We prove the following main theorem.Theorem Let u(x,t) be a local solution of problem (I),u∈C(0,T;H<sup>2</sup>(Ω)∩H<sub>0</sub><sup>1</sup>(Q)),u<sub>i</sub>∈L<sup>2</sup>(0,T;L<sup>2</sup>(Ω)), and following conditions are satisfied.(1) There exists a continuously differentiable function G(x,s) and a positive number α,such
