A Generalized Archimedean Property
We introduce and discuss a condition generalizing one of the Archimedean properties characterizing parabolas. Archimedes was familiar with the following property of parabolas: If for any two points A, B on a parabola we denote by S the area of the region between the parabola and the secant AB, and by T the maximum of the area of the triangle ABC, where C is a point on the parabola between A and...
متن کاملGeneralized Ideals in Orthoalgebras
Since in 1936 Birkhoff and von Neumann regarded the lattice of all closed subspaces of a separable infinite-dimensional Hilbert space that is an orthomodular lattice as a proposition system for a quantum mechanical entity (Miklós, 1998), orthomodular lattices have been considered as a mathematical model for a calculus of quantum logic. With the development of the theory of quantum logics, ortho...
متن کاملSome Results on a Generalized Archimedean Family of Copulas
Durante et al. (2007) introduced a class of bivariate copulas depending on two generators which generalizes some known families such as the Archimedean copulas. In this paper we provide some result on properties of this family when the generators are certain univariate survival functions.

متن کاملGENERALIZED UNI-SOFT INTERIOR IDEALS IN ORDERED SEMIGROUPS
For all M,N∈P(U) such that M⊂N, we first introduced the definitions of (M,N)-uni-soft ideals and (M,N)-uni-soft interior ideals of an ordered semigroup and studied them. When M=∅ and N=U, we meet the ordinary soft ones. Then we proved that in regular and in intra-regular ordered semigroups the concept of (M,N)-uni-soft ideals and the (M,N)-uni-soft interior ideals coincide. Finally, we introduc...
