Form uniqueness for graphs with weakly spherically symmetric ends
Luis Hernandez, Sean Ku, Jun Masamune +2
We give characterizations for the failure of form uniqueness on weakly spherically symmetric graphs. The first characterization is in terms of the graph structure, the second invol…
Essential self-adjointness of the Laplacian on weighted graphs: harmonic functions, stability, characterizations and capacity
Atsushi Inoue, Sean Ku, Jun Masamune +1
We give two characterizations for the essential self-adjointness of the weighted Laplacian on birth-death chains. The first involves the edge weights and vertex measure and is clas…
Removable sets and -uniqueness on manifolds and metric measure spaces
Michael Hinz, Jun Masamune, Kohei Suzuki
We study symmetric diffusion operators on metric measure spaces. Our main question is whether or not the restriction of the operator to a suitable core continues to be essentially…
Intrinsic ultracontractivity for domains in negatively curved manifolds
Hiroaki Aikawa, Michiel van den Berg, Jun Masamune
Let be a complete, non-compact, connected Riemannian manifold with Ricci curvature bounded from below by a negative constant. A sufficient condition is obtained for open and co…
Essential self-adjointness and the -Liouville property
Bobo Hua, Jun Masamune, Radosław K. Wojciechowski
We discuss connections between the essential self-adjointness of a symmetric operator and the constancy of functions which are in the kernel of the adjoint of the operator. We then…
A generalized conservation property for the heat semigroup on weighted manifolds
Jun Masamune, Marcel Schmidt
In this text we study a generalized conservation property for the heat semigroup generated by a Schrödinger operator with nonnegative potential on a weighted manifold. We establish…
