Equational definability of (complementary) central elements
- Mariana V. Badano and
- Diego J. Vaggione
International Journal of Algebra and Computation01 May 2016
Preview Abstract
For a variety with weak existentially definable factor congruences, we characterize when the properties “ $\to e$ $\vec{e}$ is a central element” and “ $\vec{e}$ and $\vec{f}$ are complementary central elements” are definable by $(\forall \land p = q)$ -formulas and by $(\land p = q)$ -formulas.

Birkhoff center of $c$ -semiring
- S. Kar,
- S. Purkait, and
- R. Sarkar
Asian-European Journal of Mathematics01 Feb 2019
Preview Abstract
In this paper, we introduce the concept of Birkhoff center of a $c$ -semiring and provide some characterizations of this center. Finally, we prove that the Birkhoff center of a $c$ -semiring forms a distributive lattice.

THE EXOCENTER OF A GENERALIZED PSEUDOEFFECT ALGEBRA
- S. PULMANNOVÁ
Quantitative Logic and Soft Computing01 Apr 2012
Preview Abstract
Elements of the exocenter of a generalized pseudoeffect algebra (GPEA) correspond to decompositions of the GPEA as a direct sum and thus the exocenter is a generalization to GPEAs of the center of a pseudoeffect algebra. The exocenter of a GPEA is shown to be a boolean algebra, and contains the central elements as a special subclass.
