The spectra and eigenvectors for the weighted mean matrix operator
Arab Journal of Mathematical Sciences, 2015 In this paper, first we give conditions under which the weighted mean matrix operator is bounded on the weighted Hardy spaces, and we characterize the spectrum of the weighted mean matrix operator acting on some sequence spaces.

Oscillation of Repeated Max-Weighted Power Mean Compositions of Fuzzy Matrices
Axioms, 2021 In the literature, the powers of a square fuzzy matrix with respect to the max-weighted power mean composition have been shown to always converge. This study considers the max-weighted power mean composition for a sequence of fuzzy matrices.

Bounds for the Operator Norm on Weighted Cesaro Fractional Difference Sequence Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2023 In this paper, we determine the upper and lower bounds for the norm of lower triangular matrix operators on Ces\`{a}ro weighted $(p,v)-$fractional difference sequence spaces of modulus functions.

A weighted mean Hausdorff type operator and its summability matrix domain
Journal of Inequalities and Applications, 2022 In this research, we firstly introduce a criterion for factorizing an operator based on the gamma operator, and as a result we present two factorizations for the Cesàro and Hilbert operators.

AHP-Like Matrices and Structures—Absolute and Relative Preferences
Mathematics, 2020 Aggregation functions are extensively used in decision making processes to combine available information. Arithmetic mean and weighted mean are some of the most used ones. In order to use a weighted mean, we need to define its weights.

Hybrid Linear Iterative Signal Detection Algorithm for Massive MIMO Systems
Guangtongxin yanjiu, 2022 The linear Minimum Mean Square Error (MMSE) signal detection algorithm in the massive Multiple-Input Multiple-Output (MIMO) system is difficult to use in practical engineering due to the complex inversion of the high-dimensional matrix of the signal ...

"Spectrally gapped" random walks on networks: a Mean First Passage Time formula
SciPost Physics, 2021 We derive an approximate but explicit formula for the Mean First Passage Time of a random walker between a source and a target node of a directed and weighted network.
