A study of a generalization of bi-ideal, quasi ideal and interior ideal of semigroup [PDF]

open access: yesMathematica Moravica, 2018
In this paper, as a further generalization of ideals, we introduce the notion of bi- quasi-interior ideals as a generalization of bi ideal, quasi ideal, interior ideal, bi-interior ideal and bi-quasi ideal of semigroup and study the properties of bi ...

A note on Quasi and Bi-ideals in Ternary semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
In this paper we have studied the properties of Quasi-ideals and Bi-ideals in ternary semi groups. We prove that every quasi-ideal is a bi-ideal in T but the converse is not true in general by giving several example in different context.

On quasi-ideals and bi-ideals in ternary semirings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We introduce the notions of quasi-ideal and bi-ideal in ternary semirings and study some properties of these two ideals. We also characterize regular ternary semiring in terms of these two subsystems of ternary semirings.

Passive Metasurface Tweezers for Multi-Scale Orbital Transport and Trapping on Elastic Plates. [PDF]

open access: yesAdv Sci (Weinh)
Passive labyrinthine phase encoding converts single‐channel excitation into localized flexural‐wave vortices with programmable orbital angular momentum. The resulting vortex fields enable cross‐scale particle manipulation, including orbital transport, central confinement, and rotational actuation.

Spontaneous Cyclic Levitation of Glycerol-Water Droplets at Low Pressures. [PDF]

open access: yesAdv Sci (Weinh)
Under low pressure, a minute glycerol addition transforms the chaotic dynamics of freezing water droplets into cyclic levitation. Freeze‐concentration preserves liquid pathways that relax expansion‐induced stress, while freezing point depression weakens asymmetric vaporization recoil.

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami. [PDF]

open access: yesAdv Sci (Weinh)
A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Bi-Interior Ideals of Γ-Semirings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2018
In this paper, as a further generalization of ideals, we introduce the notion of bi-interior ideal as a generalization of quasi ideal, bi-ideal and interior ideal of Γ-semiring and study the properties of bi-interior ideals of Γ-semiring.

Characterizations of Regular Ordered Semirings by Ordered Quasi-Ideals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2016
We introduce the notion of an ordered quasi-ideal of an ordered semiring and show that ordered quasi-ideals and ordered bi-ideals coincide in regular ordered semirings.

Regular Ordered Ternary Semigroups in Terms of Bipolar Fuzzy Ideals

open access: yesMathematics, 2019
Our main objective is to introduce the innovative concept of (α,ß)-bipolar fuzzy ideals and (α,ß)-bipolar fuzzy generalized bi-ideals in ordered ternary semigroups by using the idea of belongingness and quasi-coincidence of an ...
