Abstract
In this paper, the blow up of solutions for a class of nonlinear parabolic equations
with mixed boundary conditions is studied. By constructing an auxiliary function and using Hopf's maximum principles, an existence theorem of blow-up solutions, upper bound of “blow-up time” and upper estimates of “blow-up rate” are given under suitable assumptions on , initial data and suitable mixed boundary conditions. The obtained result is illustrated through an example in which are power functions or exponential functions.
