Natural partial order on rings with involution [PDF]

AKCE International Journal of Graphs and Combinatorics, 2019
In this paper, we introduce a partial order on rings with involution, which is a generalization of the partial order on the set of projections in a Rickart -ring.

Natural Partial Order on Generalized Semigroups of Transformation Semigroups That Preserve Order and an Equivalence Relation

Journal of Mathematics
Let X be a finite total order set and E be a convex equivalence relation on X. We denote that OEX=f∈TEX:∀x,y∈X,x≤y⟹fx≤fy , where TEX is an E− preserving transformation semigroup.

Semigroups for which every S-system has the natural partial order

Semigroup Forum, 1974
In this note we characterize semigroups S having the property that the relation ≤, defined by x ≤ y iff x e yS U {y}, partially orders every S-system.

Natural partial order on semigroup partial linear transformation with restricted range [PDF]

Journal of Physics: Conference Series, 2021
Abstract The set with assosiative binary operations is semigroup. Of all set partial linear transformations with a composition function is semigroup which is called a partial linear transformation semigroup that is denoted by (PT (X), o).

Partial Order Rank Features in Colour Space

Applied Sciences, 2020
Partial orders are the natural mathematical structure for comparing multivariate data that, like colours, lack a natural order. We introduce a novel, general approach to defining rank features in colour spaces based on partial orders, and show that it is
