a b s t r a c tThis paper is concerned with the blow-up of solutions to the following semilinear parabolic equation:under homogeneous Neumann boundary condition in a bounded domain Ω ⊂ R n , n ≥ 1, with smooth boundary.For all p > 1, we prove that the classical solutions to the above equation blow up in finite time when the initial energy is positive and initial data is suitably large. This result improves a recent result by Gao and Han (2011) which asserts the blow-up of classical solutions for n ≥ 3 provided that 1 < p ≤ n+2 n−2 .
