摘要
文中利用概率分布引入Trotter-Feller型算子,讨论其逼近性质,得到一系列关于Trotter-Feller型算子的逼近正定理。
In this paper, a class of new Trotter-Feller type operator and its rate of convergence are studied. A series of direct approximation theorems are obtained. The main theovem is theorem 1:Theorem 1 Let h∈Cn(R), for each x∈R and λ>0, we have
