Abstract:

The paper study the initial-boundary value problem for a class of fractional p-Laplace diffusion equation with logarithmic nonlinearity. Using the Galerkin approximation, potential well theory and Nehari manifold methods, the global existence of solutions in subcritical and critical states is proven. Then, by constructing auxiliary functions and applying differential inequality techniques, the existence of blow-up solutions in finite time is established.

Key words: fractional p-Laplacian, Galerkin approximation, the solutions for global existence, differential inequality, blow-up
