Extensions of Some Parametric Families of D(16)-Triples
Let n be an integer. A set ofm positive integers is called a D(n)-m-tuple if the product of any two of them increased by n is a perfect square. In this paper, we consider extensions of some parametric families of D(16)-triples. We prove that if {k − 4,k + 4,4k,d}, for k ≥ 5, is a D(16)-quadruple, then d = k3 − 4k. Furthermore, if {k− 4,4k,9k− 12}, for k > 5, is a D(16)-quadruple, then d = 9k3− ...

15 صفحه اولSome New Parametric Families of Multivariate Copulas
Recently, Rodríguez-Lallena and´Ubeda-Flores [8] have introduced a class of bivariate copulas which generalizes some known families such as the Farlie-Gumbel-Morgenstern distributions. In this paper we present multivariate generalizations of this class studying symmetry and dependence concepts, measuring the dependence among the components of each class, and providing several examples.
متن کاملExtensions and Degenerations of Spectral Triples
For a unital C*-algebra A, which is equipped with a spectral triple (A,H,D) and an extension T of A by the compacts, we construct a two parameter family of spectral triples (At,K,Dα,β) associated to T . Using Rieffel’s notation of quantum Gromov-Hausdorff distance between compact quantum metric spaces it is possible to define a metric on this family of spectral triples, and we show that the dis...
