Existence and uniqueness of solution for some time fractional parabolic equations involving the 1-Laplace operator

Abstract

This paper is devoted to study the time fractional parabolic 1-Laplacian type. Firstly, by using the parabolic regularization technique and approximating the parabolic 1-Laplacian problem by a class of parabolic equations of p-Laplacian type with p> 1 , we establish the existence of global weak radial solutions to the considered problem for a wide class of nonlinearities. Secondly, we discuss the extinction property of solutions to the time fractional total variation flow (FTVF) with different boundary conditions (Dirichlet and Neumann conditions). We conclude this paper by providing an example of explicit solution to the (FTVF)
