Abstract

In this paper, we study the blow-up radial solution of fully parabolic system with higher dimensional two species Cauchy problem for some initial condition. In addition, we show that the set of positive radial functions in L1(R)BUC(RN)×L1(R)BUC(RN)×W1,1(RN)W1,(RN)L^{1}(\mathbb{R})\cap BUC(\mathbb{R}^{N}) \times L^{1}(\mathbb{R})\cap BUC(\mathbb{R}^{N}) \times W^{1,1}(\mathbb{R}^{N}) \cap W^{1,\infty}(\mathbb{R}^{N}) has a dense subset composed of positive radial initial data causing blow-up in finite time with respect to topology Lp(RN)×Lp(RN)×H1(RN)W1,1(RN)L^{p}(\mathbb{R}^{N}) \times L^{p}(\mathbb{R}^{N}) \times H^{1}(\mathbb{R}^{N})\cap W^{1,1}(\mathbb{R}^{N}) for p[1,2NN+2)p \in \left[1,\frac{2N}{N+2}\right).
