Google Search Engine - Some Computing Experience
We present some results on computing a stationary probability vector of a convex combination of a large and sparse stochastic matrix and a rank one stochastic matrix. We emphasise some experiments on matrices simil...

Ordering of matrices for iterative aggregation - disaggregation methods
We show how the convergence of the iterative aggregation-disaggregation methods for computing the Perron eigenvector of a large sparse irreducible stochastic matrix can be improved by an appropriate ordering of the data and by the c...

Inverse problems for symmetric doubly stochastic matrices whose Suleimanova spectra are bounded below by 1/2
A new sufficient condition for a list of real numbers to be the spectrum of a symmetric doubly stochastic matrix is presented, this is a contribution to the classical spectral inverse problem for symmetric doubly stochastic...

Applications of Special Functions to Approximate Stochastic Bi-Homomorphisms and Stochastic Bi-Derivations in FB-Algebras and FC-⋄-Algebras of the Matrix Type
We apply special functions and use the concept of the aggregation function to introduce a new class of fuzzy control functions, and based on this, we obtain the best approximation for the stochastic bi-homomorphisms and stochastic b...

Local convergence analysis of iterative aggregation-disaggregation methods with polynomial correction
We study the iterative aggregation - disaggregation methods for computing stationary probability distribution vector of a stochastic matrix. A correction step is considered to be a polynomial in the matrix. Several converge...
