Extensions of Positive Definite Functions: Applications and Their Harmonic Analysis
Palle Jorgensen, Steen Pedersen, Feng Tian
We study two classes of extension problems, and their interconnections: (i) Extension of positive definite (p.d.) continuous functions defined on subsets in locally compact groups…

Unbounded containment in the energy space of a network and the Krein extension of the energy Laplacian
Palle E. T. Jorgensen, Erin P. J. Pearse
We compare the space of square-summable functions on an infinite graph (denoted ) with the space of functions of finite energy (denoted ). The…

Infinite weighted graphs with bounded resistance metric
Palle Jorgensen, Feng Tian
We consider infinite weighted graphs , i.e., sets of vertices , and edges assumed countable infinite. An assignment of weights is a positive symmetric function on …
