摘要:
研究了在空间逼近下各种算子分裂过程(如顺序分裂、Strang分裂和加权分裂)的收敛性。为此,证明了Chernoff乘积公式的一个变体。这些方法被应用于抽象偏时滞微分方程。
英文摘要:
The convergence of various operator splitting procedures, such as the sequential, the Strang and the weighted splitting, is investigated in the presence of a spatial approximation. To this end a variant of Chernoff's product formula is proved. The methods are applied to abstract partial delay differential equations.
