We prove convergence of a sequence of weak solutions to the nonlocal Cahn-Hilliard equation to the weak solution to the corresponding local Cahn-Hilliard equation. The analysis is done in the case of sufficiently smooth bounded domains with Neumann boundary condition and a W^{1,1}-kernel. The proof is based on an energy method. Additionally, we prove the strong L^p-convergence of the nonlocal operator to a local differential operator together with a rate of convergence. The analysis also includes more singular kernels. > References > [1] H. Abels, C. Hurm. Strong Nonlocal-to-Local Convergence of the Cahn-Hilliard Equation and its Operator. J.
