A further investigation for Egoroff's theorem with respect to monotone set functions

Kybernetika

In this paper, we investigate Egoroff’s theorem with respect to monotone set function, and show that a necessary and sufficient condition that Egoroff’s theorem remain valid for monotone set function is that the monotone set function fulfill condition (E). Therefore Egoroff’s theorem for non-additive measure is formulated in full generality.

A necessary and sufficient condition for the existence of a unique solution of a discrete boundary value problem.

Aggregation/disaggregation iterative methods applied to Leontev systems and Markov chains

Applications of Mathematics

The paper surveys some recent results on iterative aggregation/disaggregation methods (IAD) for computing stationary probability vectors of stochastic matrices and solutions of Leontev linear systems. A particular attention is paid to fast IAD methods.

An iterative algorithm for testing solvability of max-min interval systems

Kybernetika

This paper is dealing with solvability of interval systems of linear equations in max-min algebra. Max-min algebra is the algebraic structure in which classical addition and multiplication are replaced by $\oplus$ and $\otimes$, where $a\oplus b=max\left\{a,b\right\},a\otimes b=min\left\{a,b\right\}$. The notation $𝔸\otimes x=𝕓$ represents an interval system of linear equations, where $𝔸=\left[\underline{A},\overline{A}\right]$ and $𝕓=\left[\underline{b},\overline{b}\right]$ are given interval matrix and interval vector, respectively. We can define several types of solvability of interval systems. In this paper, we define the T4 and T5 solvability and give necessary and...
