摘要：
This paper is devoted to studying a nonlocal parabolic equation with logarithmic nonlinearity u log vertical bar u vertical bar - f(Omega) u log vertical bar u vertical bar dx in a bounded domain, subject to homogeneous Neumann boundary value condition. By using the logarithmic Sobolev inequality and energy estimate methods, we get the results under appropriate conditions on blow-up and non-extinction of the solutions, which extend some recent results.
