Markov uniqueness of degenerate elliptic operators

Derek W. Robinson, Adam Sikora

Let $Ω$ be an open subset of $\Ri^d$ and $H_{Ω} = - \sum_{i, j = 1}^{d} \partial_{i} c_{ij} \partial_{j}$ a second-order partial differential operator on $L_{2} (Ω)$ with domain $C_{c}^{\infty} (Ω)$ wher…

Degenerate elliptic operators in one dimension

Derek W. Robinson, Adam Sikora

Let $H$ be the symmetric second-order differential operator on $L_2(\Ri)$ with domain $C_c^\infty(\Ri)$ and action $H φ = - (c φ^{'})^{'}$ where $ c\in W^{1,2}_{\rm loc}(\Ri)$ is a real func…

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…
