Non-normality and classification of amplification mechanisms in stability and resolvent analysis [PDF]
, 2018 Eigenspectra and pseudospectra of the mean-linearized Navier-Stokes operator are used to characterize amplification mechanisms in laminar and turbulent flows in which linear mechanisms are important. Success of mean flow (linear) stability analysis for a

2×2 operator matrix with real parameter and its spectrum [PDF]
E3S Web of ConferencesIn the present paper we consider a linear bounded self-adjoint 2×2 block operator matrix Aμ (so called generalized Friedrichs model) with real parameter μ ∈ R.

The spectrum of α-resolvable λ-fold (K_4 - e)-designs
Ars Mathematica Contemporanea, 2016 A λ -fold G -design is said to be α -resolvable if its blocks can be partitioned into classes such that every class contains each vertex exactly α times. In this paper we study the α -resolvability for λ -fold ( K 4 − e ) -designs and prove that the necessary conditions for their existence are also sufficient, without any ...

On Resolvent Identities in Gaussian Ensembles at the Edge of the Spectrum
, 2008 We obtain the recursive identities for the joint moments of the traces of the powers of the resolvent for Gaussian ensembles of random matrices at the soft and hard edges of the spectrum.

Dispersive Properties of Schrödinger Equations [PDF]
, 2005 This thesis mainly concerns the dispersive properties of Schrodinger equations with certain potentials, and some of their consequences. First, we consider the charge transfer models in Rn with n > 2. In this case, the potential is a sum of several

The resolvent of a dilation-analytic three-particle system
, 1984 If the potential in a three-particle system is the boundary value of an analytic function, the physical Hamiltonian H(0) has a dilation-analytic continuation H(φ). The continuous spectrum of H(φ) consists of half-lines Y(λp, φ) starting at the thresholds

Maximum of the resolvent over matrices with given spectrum
, 2015 In numerical analysis it is often necessary to estimate the condition number $CN(T)=\left|\!\left|T\right|\!\right|_{} \cdot\left|\!\left|T^{-1}\right|\!\right|_{}$ and the norm of the resolvent $\left|\!\left|(\zeta-T)^{-1}\right|\!\right|_{}$ of a ...

Resolvent criteria for similarity to a normal operator with spectrum on a curve
, 2018 \ua9 2018 Elsevier Inc. We give some new criteria for a Hilbert space operator with spectrum on a smooth curve to be similar to a normal operator, in terms of pointwise and integral estimates of the resolvent.

Degenerate Anisotropic Differential Operators and Applications
Boundary Value Problems, 2011 The boundary value problems for degenerate anisotropic differential operator equations with variable coefficients are studied. Several conditions for the separability and Fredholmness in Banach-valued spaces are given.
