The pointwise completeness and the pointwise degeneracy of fractional descriptor discrete-time linear systems [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019 The Drazin inverse of matrices is applied to analysis of the pointwise completeness and of the pointwise degeneracy of the fractional descriptor linear discrete-time systems.

Additive Drazin inverse preservers
, 2007 Let H be a real or complex Hilbert space and B(H) denote the Banach algebra of all bounded linear operators on H. For T∈B(H), if there exists an operator TD∈B(H) and a positive integer k such thatTTD=TDT,TDTTD=TD,Tk+1TD=Tk,then T is said to be Drazin ...

The P-Drazin İnverse for Operator Matrix Over Banach Algebras [PDF]
, 2020 An element a in a Banach algebra A has p-Drazin inverse provided that there exists b2 comm(a) such that b = b2a, ak ↋ ak+1b 2 J(A) for some k 2 N. In this paper, we present new conditions for a block operator matrix to have p-Drazin inverse.

Applications of the g-Drazin Inverse to the Heat Equation and a Delay Differential Equation
Abstract and Applied Analysis, 2017 We consider applications of the g-Drazin inverse to some classes of abstract Cauchy problems, namely, the heat equation with operator coefficient and delay differential equations in Banach space.

Higher-Order Convergent Iterative Method for Computing the Generalized Inverse over Banach Spaces
Abstract and Applied Analysis, 2013 A higher-order convergent iterative method is provided for calculating the generalized inverse over Banach spaces. We also use this iterative method for computing the generalized Drazin inverse in Banach algebra.

The Natural Components of a Regular Linear System
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT The analysis of a finite‐dimensional regular linear system may be simplified by separating the system into its natural components. The natural components are smaller linear systems on separate subspaces whose dimensions sum to the dimension of the original linear system.

Are less hierarchical firms organized around stronger cultures? Evidence from big data
Strategic Management Journal, Volume 47, Issue 2, Page 463-493, February 2026.Abstract Research Summary Are less hierarchical firms organized around stronger cultures instead? We analyze 1.5 million employee reviews on Glassdoor.com from 23,000 US‐based firms, alongside data on managerial hierarchy estimated from 42 million professional social media profiles.

Facies analysis provides new insights into event bed deposition in a hadal trench environment
Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Formulae for the Generalized Drazin Inverse of a Block Matrix in Banach Algebras
Journal of Function Spaces, 2015 We present some new representations for the generalized Drazin inverse of a block matrix in a Banach algebra under conditions weaker than those used in resent papers on the subject.
