On the $l_p$ stability estimates for stochastic and deterministic difference equations and their application to SPDEs and PDEs

摘要:

在本文中,我们开发的$l_p$ -理论的时空随机差分方程,可以被认为是一个离散的对应物的N. V. Krylov的$L_p$ -理论的随机偏微分方程。我们还证明了一个Calderon-Zygmund型估计的确定性抛物型有限差分格式的系数,初始数据和强迫项放宽假设下的变系数。

英文摘要:

In this paper we develop the $l_p$-theory of space-time stochastic difference equations which can be considered as a discrete counterpart of N.V. Krylov's $L_p$-theory of stochastic partial differential equations. We also prove a Calderon-Zygmund type estimate for deterministic parabolic finite difference schemes with variable coefficients under relaxed assumptions on the coefficients, the initial data and the forcing term.
