B*-algebras over ultranormed fields
S. V. Ludkowski
This article is devoted to the investigation of -algebras, dual and annihilator ultranormed algebras. Their structure is studied in the paper. Extensions of algebras and field…
Approximation in Müntz spaces of functions for and bases
Sergey V. Ludkowski
Müntz spaces satisfying the Müntz and gap conditions are considered. A Fourier approximation of functions in the Müntz spaces of functions is studied, where $1<p<\i…
Approximation and Schauder bases in Müntz spaces of continuous functions
S. V. Ludkowski
In this article Müntz spaces of continuous functions supplied with the absolute maximum norm are considered. An approximation of functions in Müntz spaces of co…
Schauder bases in Dirac modules over quaternions
Sergey V. Ludkovsky
Dirac modules over the quaternion skew field are investigated on a compact domain relative to the supremum norm and Hardy's norm with the parameter as well. An existe…
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.
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…
