Abstract

The self-similar singular solution of the fast diffusion equation with nonlinear gradient absorption terms had been studied. By a self-similar transformation, the self-similar solutions satisfy a boundary value problem of nonlinear ODE. Using the shooting arguments, the existence and uniqueness of the solution to the initial data problem of the nonlinear ODE had been investigated, the solutions are classified by the region of the initial data. The necessary and sufficient condition for the existence and uniqueness of self-similar very singular solutions is obtained by the investigation of the classification of the solutions. In case of existence, the self-similar singular solution is very singular solution.
