A matrix variate inverse Lomax distribution

Special Matrices
This study presents the matrix variate inverse Lomax distribution as a generalization of the univariate inverse Lomax distribution and shows that this distribution can be derived by using matrix variate gamma distributions.

Alternative methods for representing the inverse of linear programming basis matrices [PDF]

, 1988
Methods for representing the inverse of Linear Programming (LP) basis matrices are closely related to techniques for solving a system of sparse unsymmetric linear equations by direct methods.

Uniform bounds on the 1-norm of the inverse of lower triangular Toeplitz matrices [PDF]

, 2011
A uniform bound on the 1-norm is given for the inverse of a lower triangular Toeplitz matrix with non-negative monotonically decreasing entries whose limit is zero. The new bound is sharp under certain specified constraints.

Matching is as easy as matrix inversion [PDF]

Proceedings of the nineteenth annual ACM conference on Theory of computing - STOC '87, 1987
This paper presents a randomized parallel algorithm which finds a maximum matching in an n-vertex m-edge graph in \(O(\log^ 2 n)\) time using \(O(n^{3.5} m)\) processors. This result improves upon the \(RNC^ 2\) algorithm of \textit{L. Lovasz} [Fundamentals of computation theory '79, Proc.

The n-inverses of a matrix

Filomat, 2017
The concept of a left n-inverse of a bounded linear operator on a complex Banach space was introduced recently. Previously, there have been results on products and tensor products of left n-inverses, and the representation of left n-inverses as the sum of left inverses and nilpotent operators was being discussed.

Inverse-designed low-index-contrast structures on silicon photonics platform for vector-matrix multiplication

, 2023
Inverse-designed Silicon photonic metastructures offer an efficient platform to perform analog computations with electromagnetic waves. However, due to computational difficulties, scaling up these metastructures to handle a large number of data channels ...

A geometrical interpretation of the inverse matrix

Journal of Inequalities and Applications, 2016
Utilizing a new method to structure parallellotopes, a geometrical interpretation of the inverse matrix is given, which includes the generalized inverse of full column rank or a full row rank matrices.
