Real Gelfand–mazur Algebras
Several classes of real Gelfand–Mazur algebras are described. Conditions, when the trace M∩B of a closed maximal left (right) idealM of a real topological algebra A would be a maximal ideal in a subalgebra B of the center of A are given.
متن کاملOn Some Inequalities in Normed Algebras
Some inequalities in normed algebras that provides lower and upper bounds for the norm of ∑n j=1 ajxj are obtained. Applications for estimating the quantities ∥∥∥∥x−1∥∥x± ∥∥y−1∥∥ y∥∥ and ∥∥∥∥y−1∥∥x± ∥∥x−1∥∥ y∥∥ for invertible elements x, y in unital normed algebras are also given.
متن کاملMazur-Ulam theorem in probabilistic normed groups
In this paper, we give a probabilistic counterpart of Mazur-Ulam theorem in probabilistic normed groups. We show, under some conditions, that every surjective isometry between two probabilistic normed groups is a homomorphism.
متن کاملOn the Mazur-Ulam problem in fuzzy anti-normed spaces
The aim of this article is to proved a Mazur-Ulam type theorem in the strictly convex fuzzy anti-normed spaces.
متن کاملNotes on normed algebras
All vector spaces and so forth here will be defined over the complex numbers. If z = x+i y is a complex number, where x, y are real numbers, then the complex conjugate of z is denoted z and defined to be x− i y. The complex conjugate of a sum or product of complex numbers is equal to the corresponding sum or product of complex conjugates. The modulus of a complex number z is the nonnegative rea...
