Convergence of symmetric diffusions on Wiener spaces

Andrea Posilicano, Tusheng Zhang

We prove convergence of symmetric diffusions on Wiener spaces by using stopping times arguments and capacity techniques. The drifts of the diffusions can be singular, we require th…

Boundary triples and Weyl functions for singular perturbations of self-adjoint operators

Andrea Posilicano

Given the symmetric operator $A_{N}$ obtained by restricting the self-adjoint operator $A$ to $N$ , a linear dense set, closed with respect to the graph norm, we determine a convenien…
