General note on the theorem of Stampfli
Journal of Inequalities and Applications, 2016 It is well known that for every bounded operator A in L ( H ) $L(H)$ , there exists a compact operator K in K ( H ) $K(H)$ such that the Weyl spectrum σ W ( A ) $\sigma_{W}(A)$ of the operator A coincides with the spectrum σ ( A + K ) $\sigma(A+K)$ of ...

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer
Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Journal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.ABSTRACT Helminths modulate host immunity, and in this respect, the porcine whipworm Trichuris suis has been explored clinically as an immunotherapy for inflammatory diseases. T. suis secretes a complex mixture of excretory/secretory products (ESP), including extracellular vesicles (EVs), nanosized membranous particles with bioactive cargoes of lipids,

Ulam-Hyers stability for partial differential inclusions
Electronic Journal of Qualitative Theory of Differential Equations, 2012 Using the weakly Picard operator technique, we will present Ulam-Hyers stability results for integral inclusions of Fredholm and Volterra type and for the Darboux problem associated to a partial differential inclusion.

Edge Density Expansions for the Classical Gaussian and Laguerre Ensembles
Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.ABSTRACT Recent work of Bornemann has uncovered hitherto hidden integrable structures relating to the asymptotic expansion of quantities at the soft edge of the Gaussian and Laguerre random matrix ensembles. These quantities are spacing distributions and the eigenvalue density, and the findings cover the cases of the three symmetry classes: orthogonal,

Introduction to Fredholm, Toeplitz and Hankel Operator [PDF]
, 2019 The whole discussion of the thesis is about Fredholm; Toeplitz; and Hankel operator. Atkinson0s theorem gives an equivalent de_nition of Fredholm operator, there we get a relation between Compact and Fredholm operator. We will learn the Calkin algebra on

A toeplitz-like operator with rational symbol having poles on the unit circle i: Fredholm properties [PDF]
, 2018 In this paper a definition is given for an unbounded Toeplitzlike operator with rational symbol which has poles on the unit circle. It is shown that the operator is Fredholm if and only if the symbol has no zeroes on the unit circle, and a formula for ...
