摘要:This paper deals with localized parabolic equations u(t) = Delta u + u(m)(x(0), t)e(pv(x0,t)), v(t) = Delta u + u(q)(x(0), t)e(nv(x0,f)) with homogeneous Dirichlet boundary conditions, where x(0) is any fixed point in a bounded domain of R(N). The optimal classification of non-simultaneous and simultaneous blow-up phenomena is proposed for all of the nonnegative exponents. Moreover, uniform blow-up profiles are obtained for all kinds of simultaneous blow-up solutions. (C) 2009 Elsevier Ltd. All rights reserved.
