Existence of weak solutions for general nonlocal and nonlinear second-order parabolic equations Original Research Article

In this article, we provide existence results for a general class of nonlocal and nonlinear second-order parabolic equations. The main motivation comes from front propagation theory in the cases when the normal velocity depends on the moving front in a nonlocal way. Among applications, we present level-set equations appearing in dislocation theory and in the study of Fitzhugh–Nagumo systems.
