High-temperature structural phase transition in multiferroic LiCu_2O_2
S. A. Ivanov, A. A. Bush, K. E. Kamentsev +4
LiCu_2O_2 single crystals were studied in the temperature range 300-1100 K by means of heating-cooling curves of differential thermal analysis (DTA), thermogravimetry (TG), X-ray p…
Operators on a non locally compact group algebra
S. V. Ludkovsky
The article is devoted to the investigation of operators on a non locally compact group algebra. Their isomorphisms are also studied.
Stationary iteration methods for solving 3D electromagnetic scattering problems
Alexander Samokhin, Yury Shestopalov, Kazuya Kobayashi
Generalized Chebyshev iteration (GCI) applied for solving linear equations with nonselfadjoint operators is considered. Sufficient conditions providing the convergence of iteration…
Magnetoelectric Interactions in Layered Composites of Piezoelectric Quartz and Magnetostrictive Alloys
G. Sreenivasulu, V. M. Petrov, L. Y. Fetisov +2
Mechanical strain mediated magnetoelectric effects are studied in bilayers and trilayers of piezoelectric quartz and magnetostrictive permendur (P), an alloy of Fe-Co-V. It is show…
Quasi-permutable normal operators in octonion Hilbert spaces and spectra
S. V. Ludkovsky
Families of quasi-permutable normal operators in octonion Hilbert spaces are investigated. Their spectra are studied. Multiparameter semigroups of such operators are considered. A…
Unbounded normal operators in octonion Hilbert spaces and their spectra
S. V. Ludkovsky
Affiliated and normal operators in octonion Hilbert spaces are studied. Theorems about their properties and of related algebras are demonstrated. Spectra of unbounded normal operat…
