Outline of Final Research Achievements

In this research project, we aim to develop the global analysis of diffusion processes on measure spaces associated with some Markov processes. The main results in this projects are (1) conservation property and recurrence of general Markov processes in terms of Green's formula (2) Characterizations of Liouville type problems of Riemannian manifolds and graphs (3) Generalized conservation property of Brownian motion with killing inside and its characterizations (4) Probabilisitic characterization of the essential selfadjointness of the Laplacian of Euclidean space removed a compact set.
