Magnetic Dual‐Layer Equivalent Sources on the Sphere
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The equivalent source method is widely used for processing and interpolating magnetic data, particularly in airborne surveys. However, implementations based on Cartesian coordinates present limitations at regional and global scales, where Earth curvature introduces geometric inconsistencies that affect data integration and modeling accuracy ...

Toeplitz operators via sesquilinear forms
, 2018 The classical theory of Toeplitz operators in spaces of analytic functions deals usually with symbols that are bounded measurable functions on the domain in question.

Bounds for Toeplitz Determinants and Related Inequalities for a New Subclass of Analytic Functions
Mathematics, 2023 In this article, we use the q-derivative operator and the principle of subordination to define a new subclass of analytic functions related to the q-Ruscheweyh operator.

Geometry of essential matrix ranges and the Smith–Ward problem for operator systems
Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.Abstract A d$d$‐tuple of bounded linear selfadjoint operators acting on an infinite‐dimensional separable Hilbert space is said to have the Smith–Ward property if the identity map of the image of the operator system in the Calkin algebra has a completely positive lift.

Toeplitz separability, entanglement, and complete positivity using operator system duality [PDF]
, 2023 A new proof is presented of a theorem of L.~Gurvits, which states that the cone of positive block-Toeplitz matrices with matrix entries has no entangled elements.

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences
Mathematische Nachrichten, Volume 299, Issue 8, Page 2087-2102, August 2026.ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

Toeplitz Operators in the Herglotz Space
, 2016 We define and study Toeplitz operators in the space of Herglotz solutions of the Helmholtz equation in . Since the most traditional definition of Toeplitz operators via Bergman-type projection is not available here, we use the approach based upon the ...
