Note on Arens regularity of symmetric tensor products

Karpatsʹkì Matematičnì Publìkacìï, 2014
We investigate symmetric regularity of sums of symmetric tensor products of Banach spaces and Arens regularity of symmetric tensor products of Banach algebras. An example for the Hilbert space is obtained.

The Differences Between Birkhoff and Isosceles Orthogonalities in Radon Planes

Extracta Mathematicae, 2017
The notion of orthogonality for vectors in inner product spaces is simple, interesting and fruitful. When moving to normed spaces, we have many possibilities to extend this notion. We consider Birkhoff orthogonality and isosceles orthogonality.

Zeros of block-symmetric polynomials on Banach spaces

Математичні Студії, 2020
We investigate sets of zeros of block-symmetric polynomials on the direct sums of sequence spaces. Block-symmetric polynomials are more general objects than classical symmetric polynomials.

Metric and Symmetric Spaces [PDF]

Proceedings of the American Mathematical Society, 1974
In this paper we give an alternative proof, without reference to Urysohn’s lemma, of the metrization theorem of Bing [2], Nagata [6], and Smirnov [8] via the theory of symmetric spaces as developed by H. Martin in [5].

Symmetric Space Cartan Connections and Gravity in Three and Four Dimensions

Symmetry, Integrability and Geometry: Methods and Applications, 2009
Einstein gravity in both 3 and 4 dimensions, as well as some interesting generalizations, can be written as gauge theories in which the connection is a Cartan connection for geometry modeled on a symmetric space.

Strongly Exponential Symmetric Spaces [PDF]

International Mathematics Research Notices, 2013
We study the exponential map of connected symmetric spaces and characterize, in terms of midpoints and of infinitesimal conditions, when it is a diffeomorphism, generalizing the Dixmier-Saito theorem for solvable Lie groups. We then give a geometric characterization of the (strongly) exponential solvable symmetric spaces as those spaces for which every

Pre-symmetric c-distances and characterization of complete cone metric spaces

Applied General Topology
The main goal of this research is to express the definition of pre-symmetric c-distances in cone metric spaces inspired by pre-symmetric w-distances defined by Romaguera and Tirado [Mathematics. 12 (2024), 2:305] and give the properties of this type of c-

Some remarks on spectra of nuclear operators

Open Mathematics, 2018
We give criteria for the spectra of some nuclear operators in subspaces of quotients of Lp-spaces to be central-symmetric, as well as for the spectra of linear operators in Banach spaces to be Zd-symmetric in the sense of B. Mityagin.

Survey on real forms of the complex A2(2)-Toda equation and surface theory

Complex Manifolds, 2019
The classical result of describing harmonic maps from surfaces into symmetric spaces of reductive Lie groups [9] states that the Maurer-Cartan form with an additional parameter, the so-called loop parameter, is integrable for all values of the loop ...
