The general solution to an autoregressive law of motion
Quantitative Economics, Volume 17, Issue 3, Page 791-826, July 2026.We provide a complete description of the set of all solutions to a vector autoregressive law of motion. Every solution is shown to be the sum of three components, each corresponding to a directed flow of time. One component flows forward from the arbitrarily distant past, one flows backward from the arbitrarily distant future, and one flows outward ...

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.

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.

A generalized Drazin inverse [PDF]
Glasgow Mathematical Journal, 1996 The main theme of this paper can be described as a study of the Drazin inverse for bounded linear operators in a Banach spaceXwhen 0 is an isolated spectral point ofthe operator. This inverse is useful for instance in the solution of differential equations formulated in a Banach spaceX.

Bordering method to compute Core-EP inverse
Special Matrices, 2018 Following the work of Kentaro Nomakuchi[10] and Manjunatha Prasad et.al., [7] which relate various generalized inverses of a given matrix with suitable bordering,we describe the explicit bordering required to obtain core-EP inverse, core-EP generalized ...

Solution of Singular Fuzzy Fraction order Control Systems via Drazin inverse
Journal of Kufa for Mathematics and Computer, 2017 In this paper , we investigate solution for singular fuzzy fractional order control system , which in turn gives us two subsystem by drazin inverse . One of these subsystems contain fuzzy fractional order control system used fuzzy laplace transform as

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 ...

Class of (n, m)-Power-D-Hyponormal Operators in Hilbert Space
International Journal of Analysis and Applications, 2020 In this paper, we introduce a new classes of operators acting on a complex Hilbert space H, denoted by [(n, m)DH], called (n, m)-power-D-hyponormal associated with a Drazin inversible operator using its Drazin inverse.
