[图书][B] Graphs and discrete Dirichlet spaces

M Keller, D Lenz, RK Wojciechowski - 2021 - Springer
The present book deals with the spectral geometry of infinite graphs. This topic involves the
interplay of three different subjects: geometry, the spectral theory of Laplacians and the heat …

Dirichlet forms and stochastic completeness of graphs and subgraphs

M Keller, D Lenz - Journal für die reine und angewandte Mathematik …, 2012 - degruyter.com
We study Laplacians on graphs and networks via regular Dirichlet forms. We give a sufficient
geometric condition for essential selfadjointness and explicitly determine the generators of …

Laplacians on infinite graphs: Dirichlet and Neumann boundary conditions

S Haeseler, M Keller, HD Lenz… - Journal of Spectral …, 2012 - ems.press
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 all …

Bipartite and neighborhood graphs and the spectrum of the normalized graph Laplacian

F Bauer, J Jost - arXiv preprint arXiv:0910.3118, 2009 - arxiv.org
We study the spectrum of the normalized Laplace operator of a connected graph $\Gamma
$. As is well known, the smallest nontrivial eigenvalue measures how difficult it is to …

Volume growth, spectrum and stochastic completeness of infinite graphs

M Keller, D Lenz, RK Wojciechowski - Mathematische Zeitschrift, 2013 - Springer
We study the connections between volume growth, spectral properties and stochastic
completeness of locally finite weighted graphs. For a class of graphs with a very weak …

[HTML][HTML] Graphs of finite measure

A Georgakopoulos, S Haeseler, M Keller… - … Mathématiques Pures et …, 2015 - Elsevier
We consider weighted graphs with an infinite set of vertices. We show that boundedness of
all functions of finite energy can be seen as a notion of 'relative compactness' for such …
