Domination of nonlinear semigroups generated by regular, local Dirichlet forms

In this article we study perturbations of local, nonlinear Dirichlet forms on arbitrary topological measure spaces. We show that the semigroup of a local Dirichlet form $\mathcal{E}$ dominates the semigroup generated by another functional $\mathcal{F}$ if, and only if, $\mathcal{F}$ is a specific zero order perturbation of $\mathcal{E}$. This helps to classify the perturbations that lie between Neumann and Dirichlet boundary conditions.
