Abstract We introduce the concept of Z-symmetric rings. In fact, the classes of all semicommutative rings, nil rings, reduced rings, Artinian rings and eversible rings are Z-symmetric rings. In order to sustain our assertion, we provide a number of examples of Z-symmetric and non Z-symmetric rings.

Polynomial Rings Over Symmetric Rings Need Not be Symmetric
Communications in Algebra, 2006Let R be a ring with identity. The polynomial ring over R is denoted by R[x] with x its indeterminate. It is shown that polynomial rings over symmetric rings need not be symmetric by an example.

For a ring endomorphism α and an α-derivation δ, we introduce weak symmetric rings and weak (α, δ)-symmetric rings which are a generalization of symmetric rings, and investigate their properties. It is proved that: (1) If R is a (α, δ)-compatible and reversible ring, then R is weak symmetric if and only if R[x; α, δ] is weak symmetric; (2) If R is a ...

Let [Formula: see text] be a ring and [Formula: see text] an idempotent of [Formula: see text], [Formula: see text] is called an [Formula: see text]-symmetric ring if [Formula: see text] implies [Formula: see text] for all [Formula: see text]. Obviously, [Formula: see text] is a symmetric ring if and only if [Formula: see text] is a [Formula: see text]

Ring properties related to symmetric rings
International Journal of Algebra and Computation, 2014The study of symmetric rings has important roles in ring theory and module theory. We investigate the structure of ring properties related to symmetric rings and introduce H-symmetric and π-symmetric as generalizations. We construct a non-symmetric reversible ring whose basic structure is infinite-dimensional, comparing with the finite-dimensional ...

Summary: Shannon suggested investigating a binary multiplying channel and asked for a maximal uniquely decodable symmetric code. Motivated by his example, we define such a code, called a Shannon set, for an arbitrary ring. We investigate the Shannon sets for the rings \(\mathbb F_q^{n\times n}\) for \(n\in\mathbb N\) and the rings \(\mathbb Z_m=\mathbb
