Boundary representation of Dirichlet forms on discrete spaces
Matthias Keller, Daniel Lenz, Marcel Schmidt +1
We describe the set of all Dirichlet forms associated to a given infinite graph in terms of Dirichlet forms on its Royden boundary. Our approach is purely analytical and uses form…

Domination of quadratic forms
Daniel Lenz, Marcel Schmidt, Melchior Wirth
We study domination of quadratic forms in the abstract setting of ordered Hilbert spaces. Our main result gives a characterization in terms of the associated forms. This generalize…
