Quasi-Compactness of Operators for General Markov Chains and Finitely Additive Measures

Autor: Alexander Zhdanok

Publikováno v: Mathematics, Vol 12, Iss 19, p 3155 (2024)

We study Markov operators T, A, and T* of general Markov chains on an arbitrary measurable space. The operator, T, is defined on the Banach space of all bounded measurable functions. The operator A is defined on the Banach space of all bounded counta

Distinguished classes of ideal spaces and their topological properties

Autor: Carmelo A. Finocchiaro, Amartya Goswami, Dario Spirito

Publikováno v: Communications in Algebra. 51:1752-1760

We consider the set of all the ideals of a ring, endowed with the coarse lower topology. The aim of this paper is to study the topological properties of distinguished subspaces of this space and detect the spectrality of some of them.

For more than one century, Aedes species are supposed to be a reservoir in dengue, yellow fever, rift valley fever and west nile viruses transmission. In this article, we study an infinite dimension ordinary differential equations system that models

Invariant densities for random continued fractions

Autor: Charlene Kalle, Valentin Matache, Masato Tsujii, Evgeny Verbitskiy

Publikováno v: Journal of Mathematical Analysis and Applications, 512(2):126163. ACADEMIC PRESS INC ELSEVIER SCIENCE

We continue the study of random continued fraction expansions, generated by random application of the Gauss and the Rényi backward continued fraction maps. We show that this random dynamical system admits a unique absolutely continuous invariant mea
