AI总结:

针对时间导数算子具有加性表示的问题,提出并研究了一类新的向量算子差分格式,通过将单个演化方程转化为方程组来实现时间推进。

摘要:

许多含时应用问题具有问题算子的加性表示。加性格式利用这种分裂构造,并基于对加性分解中各个算子的更简单问题的求解,实现到新时间层的过渡。我们考虑一类新的加性格式,用于时间导数算子具有加性表示的问题。本文构造并研究了向量算子差分格式,其特点是从一个初始演化方程过渡到这样的方程组。

英文摘要:

Many applied time-dependent problems are characterized by an additive representation of the problem operator. Additive schemes are constructed using such a splitting and associated with the transition to a new time level on the basis of the solution of more simple problems for the individual operators in the additive decomposition. We consider a new class of additive schemes for problems with additive representation of the operator at the time derivative. In this paper we construct and study the vector operator-difference schemes, which are characterized by a transition from one initial the evolution equation to a system of such equations.
