Stulken Geometry-Analysis Seminar: Heat Equation and Basic Spectral Theory of Unbounded Laplacians on Graphs
by
Daniel Lenz (Friedrich-Schiller-Universität Jena) in HB 427
We discuss Laplacians on graphs in a framework of regular Dirichlet forms. We focus on phenomena related to unboundedness of the Laplacians. In particular, we provide criteria for essential selfadjointness, empty essential spectrum and stochastic incompleteness. (Joint work with Matthias Keller).
