Global properties of Dirichlet forms in terms of Green's formula
Sebastian Haeseler, Matthias Keller, Daniel Lenz +2
We study global properties of Dirichlet forms such as uniqueness of the Dirichlet extension, stochastic completeness and recurrence. We characterize these properties by means of va…
Volume growth and bounds for the essential spectrum for Dirichlet forms
Sebastian Haeseler, Matthias Keller, Radosław K. Wojciechowski
We consider operators arising from regular Dirichlet forms with vanishing killing term. We give bounds for the bottom of the (essential) spectrum in terms of exponential volume gro…
Laplacians on infinite graphs: Dirichlet and Neumann boundary conditions
Sebastian Haeseler, Matthias Keller, Daniel Lenz +1
We study Laplacians associated to a graph and single out a class of such operators with special regularity properties. In the case of locally finite graphs, this class consists of…
