Unbounded Laplacians on Graphs: Basic Spectral Properties and the Heat Equation
Matthias Keller, Daniel Lenz
We discuss Laplacians on graphs in a framework of regular Dirichlet forms. We focus on phenomena related to unboundedness of the Laplacians. This includes (failure of) essential se…

Intrinsic metrics for non-local symmetric Dirichlet forms and applications to spectral theory
Rupert L. Frank, Daniel Lenz, Daniel Wingert
We present a study of what may be called an intrinsic metric for a general regular Dirichlet form. For such forms we then prove a Rademacher type theorem. For strongly local forms…
