摘要:

利用耦合变换和Girsanov变换,证明了一类随机广义多孔介质方程解的转移半群的无量纲Harnack不等式和强Feller性质.作为应用,给出了密度的$L^p$ -范数的上界以及相应半群的超压缩性、超压缩性和紧性.

英文摘要:

By using coupling and Girsanov transformations, the dimension-free Harnack inequality and the strong Feller property are proved for transition semigroups of solutions to a class of stochastic generalized porous media equations. As applications, explicit upper bounds of the $L^p$-norm of the density as well as hypercontractivity, ultracontractivity and compactness of the corresponding semigroup are derived.
