Blow-up behaviour for nonlinearly perturbed semilinear parabolic equations
Published online by Cambridge University Press: 14 November 2011
Extract
The blow-up behaviour of radially symmetric classical solutions to the quasilinear parabolic equation
is analysed assuming k(u) and Q(u) are small perturbations of {k, Q} ≡ {1, up},p > 1. Moreover, it is proved that the asymptotic behaviour near blowup of solutions to the semilinear equation ut = Δu + up, and in particular the final-time profile, is stable with respect to small quasilinear perturbations of the elliptic operator.
