Abstract: The author considers the solvability of the initial-boundary value problem in an n-ball for the evolution p-Laplacian equation with singular coefficients which are singular not only at the boundary of the n-ball but also at the origin x=0. The existence and nonexistence of global radial solutions are proved under some conditions related to parameters p, τ, λ and q.

Key words: Global solution, Singular coefficient, p-Laplacian equation
