Evolution of the Dependence of Residual Lifetimes [PDF]

open access: yes, 2013
We investigate the dependence properties of a vector of residual lifetimes by means of the copula associated with the conditional distribution function.

Free non-archimedean topological groups [PDF]

open access: yes, 2013
summary:We study free topological groups defined over uniform spaces in some subclasses of the class $\mathbf{NA}$ of non-archimedean groups. Our descriptions of the corresponding topologies show that for metrizable uniformities the corresponding free ...

On the resolution and linear optimization problems subject to a system of bipolar fuzzy relational equalities defined with continuous Archimedean t-norms

open access: yes
This paper considers the linear objective function optimization with respect to a more general class of bipolar fuzzy relational equations, where the fuzzy compositions are defined by an arbitrary continuous Archimedean t-norm. In addition, a faster method for finding a global optimum is proposed.

Examples of non-archimedean Fréchet spaces without nuclear Köthe quotients

open access: yes, 2008
Let K be a spherically complete non-archimedean valued field. We prove that the dual space l∞ of the Banach space c0 has a total strongly non-norming subspace M.

Decision Making by Hybrid Probabilistic - Possibilistic Utility Theory [PDF]

open access: yes
It is presented an approach to decision theory based upon nonprobabilistic uncertainty. There is an axiomatization of the hybrid probabilisticpossibilistic mixtures based on a pair of triangular conorm and triangular norm satisfying restricted ...

Representations of Archimedean t-norms in interval-valued fuzzy set theory

open access: yes, 2007
In this paper the Archimedean property and the nilpotency of t-norms on the lattice L^I is investigated, where L^I is the underlying lattice of interval-valued fuzzy set theory (Sambuc, 1975) and intuitionistic fuzzy set theory (Atanassov, 1983). We give

Strong conceptual completeness and various stability theoretic results in continuous model theory [PDF]

open access: yes, 2010
In this thesis we prove a strong conceptual completeness result for first-order continuous logic. Strong conceptual completeness was proved in 1987 by Michael Makkai for classical first-order logic, and states that it is possible to recover a first-order

Metrics and T-equalities.

open access: yes, 2002
The relationship between metrics and T-equalities is investigated; the latter are a special case of T-equivalences, a natural generalization of the classical concept of an equivalence relation.

How to make T-transitive a proximity relation

open access: yes, 2009
Three ways to approximate a proximity relation R (i.e., a reflexive and symmetric fuzzy relation) by a T -transitive one where T is a continuous Archimedean t-norm are given.

Vector lattices admitting a positively homogeneous continuous function calculus [PDF]

open access: yes, 2020
We characterize the Archimedean vector lattices that admit a positively homogeneous continuous function calculus by showing that the following two conditions are equivalent for each n-tuple x = (x_1,...,x_n)∈X^n, where X is an Archimedean vector lattice ...
