In this paper we present adaptive procedures for the numerical study of positive solutions of the following problem, ut = uxx (x, t) ∈ (0, 1)× [0, T ), ux(0, t) = 0 t ∈ [0, T ), ux(1, t) = u(1, t) t ∈ [0, T ), u(x, 0) = u0(x) x ∈ (0, 1), with p > 1. We describe two methods, the first one refines the mesh in the region where the solution becomes bigger in a precise way that allows us to recover the blow-up rate and the blow-up set of the continuous problem. The second one combine the… CONTINUE READING
