New types of bipolar fuzzy sets in -semihypergroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 The notion of bipolar fuzzy set was initiated by Lee (2000) as a generalization of the notion fuzzy sets and intuitionistic fuzzy sets, which have drawn attention of many mathematicians and computer scientists.

J-hyperideals and related generalizations in multiplicative hyperrings [PDF]
Journal of Mahani Mathematical ResearchIn this paper, we define the concept of $J$-hyperideals which is a generalization of $n$-hyperideals. A proper hyperideal $I$ of a multiplicative hyperring $R$ is said to be a $J$-hyperideal if $x,y\in R$ such that $x \circ y \subseteq I$, then ...

Scribability problems for polytopes
, 2017 In this paper we study various scribability problems for polytopes. We begin with the classical $k$-scribability problem proposed by Steiner and generalized by Schulte, which asks about the existence of $d$-polytopes that cannot be realized with all $k ...

Operations on hyperideals in ordered Krasner hyperrings
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 In the present paper, we will concentrate our efforts on ordered Krasner hyperrings and investigate some of their related properties. Moreover, we introduce and analyze the notion of interior hyperideal in ordered Krasner hyperrings. We also characterize

On Pure Hyperideals In Ternary Semihypergroups [PDF]
, 2013 This paper deals with a class of algebraic hyperstructures called ternarysemihypergroups, which are a generalization of ternary semigroups. In this paper weintroduce some special classes of hyperideals in ternary semihypergroups.

Primitive hyperideals and hyperstructure spaces of hyperrings
Categories and General Algebraic Structures with Applications, 2022 We introduce primitive hyperideals of a hyperring R and show relations with R itself, and with maximal and prime hyperideals of R. We endow a Jacobson topology on the set of primitive hyperideals of R and study topological properties of the corresponding hyperstructure space.

6j-symbols, hyperbolic structures and the Volume Conjecture
, 2007 We compute the asymptotical growth rate of a large family of $U_q(sl_2)$ $6j$-symbols and we interpret our results in geometric terms by relating them to volumes of hyperbolic truncated tetrahedra.

Polyhedral hyperbolic metrics on surfaces [PDF]
, 2018 Let S be a topologically finite surface, and g be a hyperbolic metric on S with a finite number of conical singularities of positive singular curvature, cusps and complete ends of infinite area. We prove that there exists a convex polyhedral surface P in

The $E_t$-Construction for Lattices, Spheres and Polytopes
, 2004 We describe and analyze a new construction that produces new Eulerian lattices from old ones. It specializes to a construction that produces new strongly regular cellular spheres (whose face lattices are Eulerian).
