On Fuzzy Corsini's Hyperoperations [PDF]
, 2012 We generalize the concept of C-hyperoperation and introduce the concept of F-C-hyperoperation. We list some basic properties of F-C-hyperoperation and the relationship between the concept of C-hyperoperation and the concept of F-C-hyperoperation. We also

Contributo alle iperstrutture matroidali
Le Matematiche, 1997 In this paper we continue the investigation of matroidal hyperstructures, introduced in [8], [9], [15], [17], [22]. In the first section, we define the sub-hypergroupoid [A] generated by a subset A of an hypergroupoid (H, •).

On intuitionistic fuzzy sub-hyperquasigroups of hyperquasigroups
, 2005 The notion of intuitionistic fuzzy sets was introduced by Atanassov as a generalization of the notion of fuzzy sets. In this paper, we consider the intuitionistic fuzzification of the concept of sub-hyperquasigroups in a hyperquasigroup and investigate ...

Deformation quantisation for (-1)-shifted symplectic structures and vanishing cycles [PDF]
, 2019 We formulate a notion of $E_0$ quantisation of $(-1)$-Poisson structures on derived Artin $N$-stacks, and construct a map from $E_0$ quantisations of $(-1)$-shifted symplectic structures to power series in de Rham cohomology.

Applicazioni (h,A)-lineari omomorfismi di M_A-ipergruppoidi
Le Matematiche, 1999 In the papers [9], [10] we introduced and studied M_λ -hypergroupoids; also, we obtained some results on the automorphism group of a G_ λ -hypergroupoid.

M_λ ipergruppoidi matroidali. Applicazioni λ-lineari e automorfismi di M_λ-ipergruppoidi
Le Matematiche, 1998 In this paper we forward in the investigation of the matroidal M_λ -hypergrupoids introduced in [13]. We give necessary and sufficient conditions for such hypergrupoid to be matroidal; moreover, we find its cardinality and we analyse the properties of ...

A family of 0-simple semihypergroups related to sequence A000070 [PDF]
, 2016 For any integer n 65 2, let R_0(n + 1) be the class of 0-semihypergroups H of size n + 1 such that {y} 86 xy 86 {0, y} for all x, y 08 H - {0}, all subsemihypergroups K 86 H are 0-simple and, when |K| 65 3, the fundamental relation \u3b2_K is not ...

, 2012 We present a short review of geometric and algebraic approach to causal cones and describe cone preserving transformations and their relationship with causal structure related to special and general theory of relativity.

MULTIVALUED FUNCTIONS, FUZZY SUBSETS AND JOIN SPACES
Ratio Mathematica, 2010 One has considered the Hypergroupoid Η Γ = < H;ο Γ > associated with a multivalued function Γ from H to a set D, defined as follows: ∀ x ∈ H, x ο Γ x = ⎨y⏐ Γ(y) ∩ Γ(x) ≠ ∅⎬ , ∀ (y,z) ∈ H 2 , y ο Γ z = y ο Γ y ∪ z ο Γ z , and one has calculated the fuzzy ...

, 2006 We introduce a notion of "hopfish algebra" structure on an associative algebra, allowing the structure morphisms (coproduct, counit, antipode) to be bimodules rather than algebra homomorphisms.
