Weighted MP weak group inverse

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
To extent the notion of the MP weak group inverse for square matrices, we introduce the concept of the weighted MP weak group inverse for rectangular matrices.

Inverse Ambiguous Functions and Automorphisms on Finite Groups

Annales Mathematicae Silesianae, 2019
If G is a finite group, then a bijective function f : G → G is inverse ambiguous if and only if f(x)−1 = f−1(x) for all x ∈ G. We give a precise description when a finite group admits an inverse ambiguous function and when a finite group admits an ...

The Inverse of Exact Renormalization Group Flows as Statistical Inference

Entropy
We build on the view of the Exact Renormalization Group (ERG) as an instantiation of Optimal Transport described by a functional convection–diffusion equation.

The m-weak core inverse relative to a Hermitian weight

Demonstratio Mathematica
In this paper, we introduce the concept of E-relative m-weak core inverse of a square matrix as a common extension of the E-weighted core-EP inverse and the m-weak core inverse.

Machine learning models predict the emergence of depression in Argentinean college students during periods of COVID-19 quarantine

Frontiers in Psychiatry
IntroductionThe COVID-19 pandemic has exacerbated mental health challenges, particularly depression among college students. Detecting at-risk students early is crucial but remains challenging, particularly in developing countries.

The Semigroup and the Inverse of the Laplacian on the Heisenberg Group

Cubo, 2010
By decomposing the Laplacian on the Heisenberg group into a family of parametrized partial differential operators Lt ,t ∈ R {0}, and using parametrized Fourier-Wigner transforms, we give formulas and estimates for the strongly continuous one ...
