Fractals, 2023
Being a useful technique for solving differential equation, the study investigated the utility/efficiency of Natural Transform coupled with Adomian Decomposition Method (NADM). For this purpose, one-dimensional (1D) fuzzy fractional-order heat equation was split into two hybrid equations consisting of upper and lower solutions by the fast technique ...

Quasiresiduals in Semigroups with Natural Partial Order
Algebra Colloquium, 2017A semigroup (S, ·) is called right (left) quasiresiduated if for any a, b in S there exists x in S such that ax ≤S b (xa ≤S b) with respect to the natural partial order ≤S of S. This concept has its origin in the theory of residuated semigroups, but can also be seen as a generalization of the right (left) simplicity of semigroups.

Naturally Ordered Semigroups of Partial Transformations Preserving an Equivalence Relation
Communications in Algebra, 2013Let X be a set with |X| ≥3, P(X) the semigroup of all partial transformations on the set X, E be an equivalence relation on X, and Then P E (X) forms a subsemigroup of P(X). In this article, we consider the natural order ≤on P E (X) and determine when two elements of P E (X) are related under this order.

THE NATURAL PARTIAL ORDER ON LINEAR SEMIGROUPS WITH NULLITY AND CO-RANK BOUNDED BELOW
Bulletin of the Australian Mathematical Society, 2014AbstractHiggins [‘The Mitsch order on a semigroup’, Semigroup Forum 49 (1994), 261–266] showed that the natural partial orders on a semigroup and its regular subsemigroups coincide. This is why we are interested in the study of the natural partial order on nonregular semigroups.

Natural congruences and isomorphism theorems for directed complete partially ordered sets
Algebra universalis, 2017It was shown by \textit{T. S. Blyth} and \textit{M. F. Janowitz} in [Residuation theory. Oxford etc.: Pergamon Press. (1972; Zbl 0301.06001)] that an equivalence \(R\) on an ordered set is a congruence, i.e. the quotient structure is an ordered set again, if and only if \(R\) is convex. Directed complete partially ordered sets play an important role in

Natural Partial Orders on Division Rings with Involution
1993This article studies intrinsic or natural partial orders on involutive division rings (D,*, II), where (a + b)* = a* + b*, (ab)* = b*a*, a** = a for a, b ∈ D, and where II is the strictly positive cone for an additive partial group order on (D, +). The involution defines several natural multiplicative subgroups G ⊂ D\ 0, and the positive cones are ...

Classes of semigroups with compatible natural partial order. I.
Mathematica Pannonica, 2011Summary: In this survey we find new semigroups and collect all semigroups known up to now that have a right (two-sided) compatible natural partial order. In this first part trivially, resp. totally, ordered semigroups are considered and semigroups in special classes -- in particular (E-)medial semigroups -- with this property are studied.
