Representations for the Generalized Drazin Inverse of the Sum in a Banach Algebra and Its Application for Some Operator Matrices [PDF]
The 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.

Model order reduction for bifurcating phenomena in fluid-structure interaction problems. [PDF]
Int J Numer Methods Fluids, 2022 The nonlinearity of a partial derivative equation can produce the onset of bifurcation phenomena, which play a key role in the study of physical and engineering systems, as they can lead to deviation from nominal operating conditions. This perspective discusses a bifurcation phenomenon, known as the Coandă effect, which can be observed in a cardiac ...

B-Fredholm Spectra of Drazin Invertible Operators and Applications
Axioms, 2021 In this article, we consider Drazin invertible operators for study of the relationship between their B-Fredholm spectra and the transfer between some of the spectral properties defined through B-Fredholm spectra of this class of operators.

Cascading innovation: R&D team design and performance implications of mobility
Strategic Management Journal, Volume 44, Issue 5, Page 1218-1253, May 2023., 2023 Abstract Research Summary Given the high cost of external hiring and uncertainty related to performance benefits, how can organizations foster an environment that maximizes the post‐mobility performance of external hires and their collaborators? In this article, I posit that R&D team design is an important factor that could shape the post‐mobility ...

Estimating the Meridional Extent of Adiabatic Mixing in the Stratosphere Using Age‐Of‐Air
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 4, 27 February 2023., 2023 Abstract Wave‐induced adiabatic mixing in the winter midlatitudes is one of the key processes impacting stratospheric transport. Understanding its strength and structure is vital to understanding the distribution of trace gases and their modulation under a changing climate.

Algebraic Perturbation Theorems of Core Inverse A㊮ and Core‐EP Inverse A㊯
Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 In this paper, the algebraic perturbation theorems of the core inverse A㊮ and core‐EP inverse A㊯ are discussed for a square singular matrix A with different indices, and the expressions of the algebraic perturbation for these two new generalized inverses are presented. As their applications, some properties of the core inverse A㊮ and core‐EP inverse A㊯

New Characterizations and Representations of the Bott–Duffin Inverse
Journal of Mathematics, Volume 2023, Issue 1, 2023., 2023 The paper focuses on the class of the Bott–Duffin inverses. Several original features of the class are identified and new properties are characterized. Some of the results available in the literature are recaptured in a more general form. BD matrices are also introduced and some properties are given.

Optimal Taxation of Income‐Generating Choice
Econometrica, Volume 90, Issue 5, Page 2397-2436, September 2022., 2022 Discrete location, occupation, skill, and hours choices of workers underpin their incomes. This paper analyzes the optimal taxation of discrete income‐generating choice. It derives optimal tax equations and Pareto test inequalities for mixed logit choice environments that can accommodate discrete and unstructured choice sets, rich preference ...
