Hyperchaotic Behavior in the Novel Memristor-Based Symmetric Circuit System

open access: yesIEEE Access, 2020
A novel five-dimensional (5D) memristor-based symmetric circuit, which consists of two symmetric capacitors, two symmetric inductors and only one memristor is presented in this article.

Symmetric Busemann functions [PDF]

open access: yesPacific Journal of Mathematics, 2001
A result connecting symmetric spaces on one hand and symmetry of Busemann functions and the co-ray relation on the other is proved. This result is applied to hyperbolic and Minkowski geometries.

Fractional q-symmetric calculus on a time scale

open access: yesAdvances in Difference Equations, 2017
In this paper, the definitions of q-symmetric exponential function and q-symmetric gamma function are presented. By a q-symmetric exponential function, we shall illustrate the Laplace transform method and define and solve several families of linear ...

Complex-valued symmetric radial basis function network for beamforming

open access: yes, 2009
The complex-valued radial basis function (RBF) network proposed by Chen et al. (1994) has found many applications for processing complex-valued signals, in particular, for communication channel equalization and signal detection.

On Symmetric Functions and Symmetric Functions of Symmetric Functions

open access: yesThe Annals of Mathematical Statistics, 1931
The study of symmetric functions is quite an old one. From the time of Girard (1629) even up to the present day this sub. ject has occupied the attention of many eminent mathematicians. The theory of the roots of algebraic equations in one or more variables has furnished the chief incentive for the development of the theory of symmetric functions ...

Isomorphisms of algebras of symmetric functions on spaces $\ell_p$

open access: yesМатематичні Студії
The work is devoted to the study of algebras of entire symmetric functions on some Banach spaces of sequences. A function on a vector space is called symmetric with respect to some fixed group $G$ of operators acting on this space, or $G$-symmetric, if ...

Continuous block-symmetric polynomials of degree at most two on the space $(L_\infty)^2$

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2016
We introduce block-symmetric polynomials on $(L_\infty)^2$ and prove that every continuous block-symmetric polynomial of degree at most two on $(L_\infty)^2$ can be uniquely represented by some "elementary" block-symmetric polynomials.

A categorification of the chromatic symmetric polynomial [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2015
The Stanley chromatic polynomial of a graph $G$ is a symmetric function generalization of the chromatic polynomial, and has interesting combinatorial properties.
