C∗-algebraic Gauss-Lucas Theorem and C∗-algebraic Sendov’s Conjecture

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Building on a foundational result established by Robertson [Proc. Edinburgh Math. Soc., 1976], we develop a framework for differentiation of maps defined on specific classes of unital commutative C∗-algebras.

Parity of ranks of Jacobians of curves

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 3, September 2025.
Abstract We investigate Selmer groups of Jacobians of curves that admit an action of a non‐trivial group of automorphisms, and give applications to the study of the parity of Selmer ranks. Under the Shafarevich–Tate conjecture, we give an expression for the parity of the Mordell–Weil rank of an arbitrary Jacobian in terms of purely local invariants ...

MARTApp: software for the processing and reconstruction of synchrotron‐radiation‐based magnetic tomographies

open access: yesJournal of Synchrotron Radiation, Volume 32, Issue 4, Page 1095-1104, July 2025.
MARTApp is an open‐source software for magnetic vector reconstruction of the data acquired from magnetic transmission X‐ray microscopy. It automates the tasks of image normalization, alignment, computation of magnetic signal and the reconstruction of quasi‐2D and ‐3D systems.

Linearization routines for the parameter space concept to determine crystal structures without Fourier inversion

open access: yesJournal of Applied Crystallography, Volume 58, Issue 3, Page 768-788, June 2025.
Novel linearization routines within the parameter space concept (PSC) provide an alternative approach to determine one‐dimensionally projected crystal structures from a few diffraction intensities of standard Bragg reflections, represented by piecewise analytic hyper‐surfaces, without the use of Fourier inversion.

2-Homogeneous C*-algebras with the space of primitive ideals homeomorphic to a two-dimensional oriented compact connected manifold generated by idempotents

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2018
Before showed in 1961 that every n-homogeneous C*-algebra is isomorphic to the algebra of all continuous sections for the appropriate algebraic bundle. The base space for the bundle is homeomorphic to the space of primitive ideals for the algebra in the ...
