Singular Semilinear Reaction Diffusion Equations Of The Cauchy Problem

In this paper,we study the Cauchy problem of semilinear singular reaction-diffusion system with Semigrap of operator,namely, Where p>0,q>0,N≥1,fi(x) (i=1,2) are nonnegative continuous and bounded functions.Δis N dimension laplace operator. and give some results: Then every nontrivial solution of (1) in L∞(RN) blows up in finite time. Then every nontrivial solution of (1) in L∞(RN) blows up in finite time. Then every nontrivial solution of (1) in L∞(RN) blows up in finite time.
