Contraction semigroups on $L_{\infty} (R)$

Derek W. Robinson, A. F. M. ter Elst

If $X$ is a non-degenerate vector field on $R$ and $H = - X^{2}$ we examine conditions for the closure of $H$ to generate a continuous semigroup on $L_{\infty}$ which extends to the…

Small time asymptotics of diffusion processes

A. F. M. ter Elst, Derek W. Robinson, Adam Sikora

We establish the short-time asymptotic behaviour of the Markovian semigroups associated with strongly local Dirichlet forms under very general hypotheses. Our results apply to a wi…
