On a class of generated triangular norms and their isomorphisms

Fuzzy Sets and Systems, 2010
Let \(f_1\) and \(f_2\) be two strictly decreasing additive generators of border-continuous triangular norms \(T_1\) and \(T_2\), respectively. Necessary and sufficient conditions on \(f_1,f_2\) are given in order to ensure that the semigroups \(([0,1],T_1)\) and \(([0,1],T_2)\) are isomorphic. The conditions are expressed in terms of the ranges of the

Isomorphism Classes of Solenoidal Algebras I

Canadian Mathematical Bulletin, 1993
AbstractEach g ∊ ℤ[x] defines a homeomorphism of a compact space We investigate the isomorphism classes of the C*-crossed product algebra Bg associated with the dynamical system An isomorphism invariant Eg of the algebra Bg is shown to determine the algebra Bg up to * or * anti-isomorphism if degree g ≤ 1 and 1 is not a root of g or if degree g = 2 ...

On the Isomorphism Classes of Transversals-II

Communications in Algebra, 2011
In this article we prove that there does not exist a subgroup H of a finite group G such that the number of isomorphism classes of right transversals of H in G is two.

The isomorphism class of a set of lattices

Mathematical Proceedings of the Cambridge Philosophical Society, 1989
AbstractLet R be a Dedekind domain with field of quotients K. Let A be a finite-dimensional K-algebra. We consider isomorphism classes and genera in a category whose objects are indexed sets of full R-lattices in some ambient A-module and whose morphisms are the A-homomorphisms of the ambient A-modules which map each lattice into its corresponding ...

Isomorphism classes in finite partial hypergroupoids of class two

1996
Let \(H\) be a set with \(n\) elements and \(\circ\colon H\times H\to{\mathcal P}(H)\) be a partial hyperoperation on \(H\). If the set \(\{(a,b)\in H^2\mid a\circ b\neq\emptyset\}\) has \(k\) elements, where \(k\in\{0,1,\dots,n^2\}\), then the partial hypergroupoid \((H,\circ)\) is said to be of class \(k\).
