Flows and invariance for elliptic operators

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

Let $S$ be the submarkovian semigroup on $L_{2} (R^{d})$ generated by a self-adjoint, second-order, divergence-form, elliptic operator $H$ with $W^{1, \infty}$ coefficients $c_{kl}…

Conservation and invariance properties of submarkovian semigroups

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

Let $E$ be a Dirichlet form on $L_{2} (X)$ and $Ω$ an open subset of $X$ . Then one can define Dirichlet forms $E_{D}$ , or $E_{N}$ , corresponding to $E$ but wit…

Ellipticity and Ergodicity

Derek W. Robinson, Adam Sikora

Let $S = {S_{t}}_{t \geq 0}$ be the submarkovian semigroup on $L_2(\Ri^d)$ generated by a self-adjoint, second-order, divergence-form, elliptic operator $H$ with Lipschitz continuous c…

Positivity and strong ellipticity

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

We consider second-order partial differential operators $H$ in divergence form on $\Ri^d$ with a positive-semidefinite, symmetric, matrix $C$ of real $L_{\infty}$ -coefficients and es…
