Abstract:

This paper investigates the self-similar singular solution of the p-Laplacian evolution equation with the nonlinear gradient absorption terms u_t=div(|∇u|^p-2∇u)-|∇u|^q for 1<p<2 and q>1 in Rⁿ×(0, ∞). It has been proved that when 1<q<p-n/(n+1) there exists a unique self-similar very singular solution.
