Abstract

The paper contains necessary and sufficient conditions under which the ergodic principle and the regularity condition hold for discrete quantum quadratic stochastic processes defined on von Neumann algebras. A connection between these processes and Markov processes is established.

On expansion of quantum quadratic stochastic processes into fibrewise Markov processes defined on von Neumann algebras

Farrukh Maksutovich Mukhamedov

We give an expansion of a quantum quadratic stochastic process (q. q. s. p.) into a so-called fibrewise Markov process and prove that, conversely, such an expansion uniquely determines the quantum quadratic stochastic process. As an application, we give a criterion (in terms of this expansion) for the q. q. s. p. to satisfy the ergodic principle. Using this result, we prove that a q. q. s. p. satisfies the ergodic principle if and only if the associated Markov process satisfies this prin- ciple. The expansion obtained is used to introduce a new notion of conjugacy of two q. q. s. p.'s and to study the relation between this notion and the ergodic principle.

ON MARGINAL MARKOV PROCESSES OF QUANTUM QUADRATIC STOCHASTIC PROCESSES

Farrukh Maksutovich Mukhamedov

In the paper it is defined two marginal Markov processes on von Neumann algebras $\cm$ and $\cmø\cm$, respectively, corresponding to given quantum quadratic stochastic process (q.q.s.p.). It is proved that such marginal processes uniquely determines the q.q.s.p. Moreover, certain ergodic relations between them are established as well.

On the ergodic principle for Markov processes associated with quantum quadratic stochastic processes

Farrukh Maksutovich Mukhamedov

In [1] the non-stationaryMarkov process generated by a quantum quadratic stochastic process (QQSP) was defined, and it was noted that if the QQSP satisfies the ergodic principle, then so does the Markov process. In the present article we use a decomposition of a QQSP (see [2]) to prove that the converse is also true, that is, if the Markov process satisfies the ergodic principle, then so does the corresponding QQSP.

A Survey on Invariance and Ergodicity of Quantum Markov Semigroups

Mou-Hsiung Chang

This article surveys recent results on invariances and ergodicity of general quantum Markov semigroups of bounded linear maps acting on C*- or von Neumann algebra . In particular, we consider existence and uniqueness of invariant (stationary) quantum states as well as ergodicity and mean ergodicity of quantum states via heavy usage of the GNS representation. This survey is made self-contained by also reviewing relevant concepts and results necessary for the subsequent developments.
