Critical generalized inverse participation ratio distributions

open access: yes, 2002
The system size dependence of the fluctuations in generalized inverse participation ratios (IPR's) $I_{\alpha}(q)$ at criticality is investigated numerically.

Inverse problem for Dirac systems with locally square-summable potentials and rectangular Weyl functions [PDF]

open access: yes, 2014
Inverse problem for Dirac systems with locally square summable potentials and rectangular Weyl functions is solved. For that purpose we use a new result on the linear similarity between operators from a subclass of triangular integral operators and the ...

Representations for the Generalized Drazin Inverse of the Sum in a Banach Algebra and Its Application for Some Operator Matrices

open access: yesThe Scientific World Journal, 2015
We investigate additive properties of the generalized Drazin inverse in a Banach algebra A. We find explicit expressions for the generalized Drazin inverse of the sum a+b, under new conditions on a,b∈A.

An efficient hyperpower iterative method for computing weighted MoorePenrose inverse

open access: yesAIMS Mathematics, 2020
In this paper, we propose a new hyperpower iterative method for approximating the weighted Moore-Penrose inverse of a given matrix. The main objective of the current work is to minimize the computational complexity of the hyperpower iterative method ...

The Forward Order Law for Least Squareg-Inverse of Multiple Matrix Products

open access: yesMathematics, 2019
The generalized inverse has many important applications in the aspects of the theoretic research of matrices and statistics. One of the core problems of the generalized inverse is finding the necessary and sufficient conditions of the forward order laws ...

Obstacle Avoidance in Operational Configuration Space Kinematic Control of Redundant Serial Manipulators

open access: yesMachines, 2023
Kinematic control of redundant serial manipulators has been carried out for the past half century based primarily on a generalized inverse velocity formulation that is known to have mathematical deficiencies.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Distribution Of Wealth In A Network Model Of The Economy

open access: yes, 2012
We show, analytically and numerically, that wealth distribution in the Bouchaud-M\'ezard network model of the economy is described by a three-parameter generalized inverse gamma distribution.
