开KPZ方程的强Feller性质

The strong Feller property of the open KPZ equation

Alisa Knizel, Konstantin Matetski

摘要:

证明了有界空间区间上的开KPZ方程所生成的具有实参数u和v的Neumann边界条件的半群具有强Feller性质.由此我们得出结论:当u+v>0,min(u,v)>-1时,Corwin和Knizel(arXiv:2103.12253)构造的平稳测度是方程的唯一平稳测度.预期相同的结论对于u和v的所有值都成立。

英文摘要:

We prove that the semigroup generated by the open KPZ equation on a bounded spatial interval with Neumann boundary conditions parametrized by real parameters u and v enjoys the strong Feller property. From this we conclude that for u+v>0, min(u,v)>-1 the stationary measure constructed in Corwin and Knizel (arXiv:2103.12253) is the unique stationary measure for the equation. It is expected that the same conclusion holds for all values of u and v.
