Abstract
In this paper we give an existence theorem of global classical solution to the initial boundary value problem for the quasilinear parabolic equations of divergence form utâdiv{Ï(|âu|2)âu}=f(âu,u,x,t) where Ï(|âu|2) may not be bounded as |âu|ââ. As an application the logarithmic type nonlinearity Ï(|âu|2)=logâ¡(1+|âu|2) which is growing as |âu|ââ and degenerate at |âu|=0 is considered under fâ¡0.
