Dihedral transportation and (0, 1)-matrix classes [PDF]

open access: yesLinear and Multilinear Algebra, 2017
Let R and S be two vectors of real numbers whose entries have the same sum. In the transportation problems one wishes to find a matrix A with row sum vector R and column sum vector S. If, in addition, the two vectors only contain nonnegative integers then one wants the same to be true for A.

Hierarchical CNN Classification of Hyperspectral Images Based on 3-D Attention Soft Augmentation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The distinction of similar classes has always been the core issue in image classification. In this article, a new hierarchical classification process based on three-dimensional attention soft augmentation (HC-3DAA) is proposed to improve the accuracy of ...

A New Paranormed Sequence Space Defined by Regular Bell Matrix

open access: yesDera Natung Government College Research Journal, 2023
This paper aims to construct a new paranormed sequence space by the aid of a regular matrix of Bell numbers. As well, its special duals such as α−,β−,γ−  duals are presented and Schauder basis is determined.

Interpolation classes and matrix means [PDF]

open access: yesBanach Journal of Mathematical Analysis, 2015
Using a `local' integral representation of a matrix connection of order $n$ corresponding to an interpolation function of the same order, for each integer $n$, we can describe an injective map from the class of matrix connections of order $n$ to the class of positive $n$-monotone functions on $(0,\infty)$ and the range of this corresponding covers the ...

Duals and Matrix Classes Involving Cesàro Type Classes of Sequences of Fuzzy Numbers

open access: yesAdvances in Fuzzy Systems, 2018
We first define Cesàro type classes of sequences of fuzzy numbers and equip the set with a complete metric. Then we compute the Köthe-Toeplitz dual and characterize some related matrix classes involving such classes of sequences of fuzzy numbers.

Two New Matrix Classes Related to the CMP Inverse: CMP and Co-CMP Matrices

open access: yesMathematics, 2023
This paper focuses on two new matrix classes related to the CMP inverse of a square matrix, called the CMP and co-CMP matrices. Some of their characterizations are identified based on the core-EP decomposition and subspace operations.

The Hadamard Product of a Nonsingular General H-Matrix and Its Inverse Transpose Is Diagonally Dominant

open access: yesJournal of Applied Mathematics, 2015
We study the combined matrix of a nonsingular H-matrix. These matrices can belong to two different H-matrices classes: the most common, invertible class, and one particular class named mixed class.
