On a nonlinear parabolic equation with fractional Laplacian and integral conditions

Abstract

The paper deals with non-classical initial-boundary value problems for parabolic equations with a fractional Laplacian. We study the existence and uniqueness of a mild solution to our problem. The continuous dependence of the solution on the given data is shown and the ill-posedness of the mild solution at t = 0 is also considered. In order to avoid such ill-posedness, we construct a regularized solution using the Fourier truncation method. An error estimate and the convergence rate between the regularized solution and the exact solution are obtained.
