Stationary Markovian Decision Problems and Perturbation Theory of Quasi-Compact Linear Operators

Mathematics of Operations Research, 1977
In this paper stationary Markov decision problems are considered with arbitrary state space and compact space of strategies. Conditions are given for the existence of an average optimal strategy. This is done by using the fact that a continuous function on a compact space attains its minimum.

Low-order scaling local correlation methods II: Splitting the Coulomb operator in linear scaling local second-order Møller–Plesset perturbation theory

The Journal of Chemical Physics, 2000
A novel multipole approximation for the linear scaling local second-order Møller–Plesset perturbation theory (MP2) method is presented, which is based on a splitting of the Coulomb operator into two terms. The first one contains the singularity and is rapidly decaying with increasing distance. It is treated by a conventional two-electron transformation,

An abstract analog of the krylov-bogolyubov transformation in the perturbation theory of linear operators

Functional Analysis and Its Applications, 1999
UDC 517.9 Let ~'be a Bmlach space over a field K E {R,C}, and let B(a,p) be the open ball in ~'with center a E ~" and radius p > 0. By Lipk(~ a, p), k E NU {0}, we denote the Banach space of continuous mappings (operators) defined on the closed ball B(a, p) = B(a, p), ranging in ~'.
