Browder S-resolvent equation in quaternionic setting [PDF]
, 2023 This paper is devoted to the study of the S-eigenvalue of finite type of a bounded right quaternionic linear operator acting in a right quaternionic Hilbert space. The study is based on the different properties of the Riesz projection associated with the

Properties and for Bounded Linear Operators
Journal of Mathematics, 2013 We shall consider properties which are related to Weyl type theorem for bounded linear operators , defined on a complex Banach space . These properties, that we call property , means that the set of all poles of the resolvent of of finite rank in the ...

Resolvent for Non-Self-Adjoint Differential Operator with Block-Triangular Operator Potential
Abstract and Applied Analysis, 2016 A resolvent for a non-self-adjoint differential operator with a block-triangular operator potential, increasing at infinity, is constructed. Sufficient conditions under which the spectrum is real and discrete are obtained.

Eigenvalue estimates for operators with finitely many negative squares [PDF]
Opuscula Mathematica, 2016 Let \(A\) and \(B\) be selfadjoint operators in a Krein space. Assume that the resolvent difference of \(A\) and \(B\) is of rank one and that the spectrum of \(A\) consists in some interval \(I\subset\mathbb{R}\) of isolated eigenvalues only.

Phase-resolved spectrum of the Crab pulsar from NICER [PDF]
Astronomy & Astrophysics, 2021 Context. Studies of the high-energy emission regions of rotation-powered pulsars are typically based on folded light curves (FLCs) and phase-resolved spectra (PRS). Aims. This work uses the NICER observatory to obtain the highest resolution FLC and PRS of the Crab pulsar at soft X-ray energies. Methods.

On the structure and origin of pressure fluctuations in wall turbulence: predictions based on the resolvent analysis [PDF]
, 2014 We generate predictions for the fluctuating pressure field in turbulent pipe flow by re-formulating the resolvent analysis of McKeon & Sharma (2010) in terms of the so-called primitive variables. Under this analysis, the nonlinear convective terms in

Opposition control within the resolvent analysis framework [PDF]
, 2014 This paper extends the resolvent analysis of McKeon & Sharma (2010) to consider flow control techniques that employ linear control laws, focusing on opposition control (Choi et al. 1994) as an example.

Open Mathematics, 2023 In this article, we focus on the scattering analysis of Sturm-Liouville type singular operator including an impulsive condition and turning point. In the classical literature, there are plenty of papers considering the positive values of the weight ...

On the Spectrum of Non-Selfadjoint Schrödinger Operators with Compact Resolvent [PDF]
Communications in Partial Differential Equations, 2015 We determine the Schatten class for the compact resolvent of Dirichlet realizations, in unbounded domains, of a class of non-selfadjoint differential operators. This class consists of operators that can be obtained via analytic dilation from a Schrödinger operator with magnetic field and a complex electric potential.
