... solution of (2.28) correspond-ing to (v1(x, t),u1(x, t)) ∈X. To use Schauder’s fixed point theorem, we need to verify thefact that Y maps X into itself is continuous and compact. In fact, ... certain conditions, it is proved thatthe blowup set of the solution is the whole domain. In this paper, we generalize the results of [6] to parabolic system and investigate theeffect of the singularity, ... M in (0,a).Theorem 3.7. Under the assumptions of (H) and Case 2, if the solution of (1.1)blowsupat the point x0∈ (0,a), then the blowup set of the solution of (1.1)is[0,a].Proof. The proof...
