On stable b-bistochastic quadratic stochastic operators and associated non-homogenous Markov chains

Abstract

Abstract. In the present paper, we consider a class of quadratic stochastic operators (q.s.o.) called b−bistochastic q.s.o. We include several properties of b−bistochastic q.s.o. and their dynamical behavior. One of the main findings in this paper is the description on the uniqueness of the fixed points. Besides, we list the conditions on strict contractive b−bistochastic q.s.o. on low dimensional simplices and it turns out that, the uniqueness of the fixed point does not imply strict contraction. Finally, we associated Markov measures with b-bistochastic q.s.o. On a class of b-bistochastic q.s.o. on finite dimensional simplex, the defined measures were proven to satisfy the mixing property. Moreover, we show that Markov measures associated with a class of b−bistochastic q.s.o on one dimensional simplex meets the absolute continuity property.Mathematics Subject Classification: 46L35, 46L55, 46A37.

On Discrete-Time Models of Network Worm Propagation Generated by Quadratic Operators

“…Such operators occur in some models of mathematical biology and describe the evolution of a population consisting of several types of individuals (see e.g., [1,4,9,10,11,12,13,14,15,17,19,21,22,23,24,26]). Assume that {x (n) ∈ S m−1 : n = 0, 1, 2, .…”

Genetic Algebras generated by b−bistochastic Quadratic Stochastic Operators: The Character and Associativity

“…Taking into account (19), one can check that (20), ( 21) and ( 26) are the same. Moreover, (22) and ( 24) are clearly equivalent.…”

“…We point out that, the considered class of QSO's is a generalization to the concept of majorization that was popularized by Hardy, Littlewood and Polya [10]. Dynamical properties of b−bistochastic QSOs could be further referred to [15,19]. This paper is organized as follows: Section 2 is devoted to preliminary definitions and notations throughout this paper.…”

Quadratic stochastic operators on Banach lattices

“…The list of very recent articles and online presentations is long. Let us only mention [18,19,25,26], where the notion of quadratic stochastic operators is put into abstract vector (Banach) spaces with specific order or norm structures. In [24] the author studies nonhomogeneous Markov chains on ordered Banach spaces which are strongly linked to some picture of quadratic stochastic operators.…”
