Defects and transformations of quasi-copulas [PDF]
, 2016 summary:Six different functions measuring the defect of a quasi-copula, i. e., how far away it is from a copula, are discussed. This is done by means of extremal non-positive volumes of specific rectangles (in a way that a zero defect characterizes ...

Open problems posed at the eighth international conference on fuzzy set theory and applications [PDF]
, 2006 summary:Several open problems posed during FSTA 2006 (Liptovský Ján, Slovakia) are presented. These problems concern the classification of strict triangular norms, Lipschitz t-norms, interval semigroups, copulas, semicopulas and quasi- copulas, fuzzy ...

Uogólnione schematy i reguły wnioskowania w logice rozmytej [PDF]
, 2020 In Chapter 1 we recall the most important notions in the theory of fuzzy sets. In Chapter 2 we give some basic facts regarding approximate reasoning. In the main part of the thesis we consider functional equations and inequalities mentioned above when

A primer on triangle functions II [PDF]
, 2010 In [32] we presented an overview of concepts, facts and results on triangle functions based on the notions of t-norm, copula, (generalized) convolution, semicopula, quasi-copula. Here, we continue our presentation.

Constructing copulas by means of pairs of order statistics [PDF]
, 2009 summary:In this paper, we introduce two transformations on a given copula to construct new and recover already-existent families. The method is based on the choice of pairs of order statistics of the marginal distributions.

Copulas with given values on a horizontal and a vertical section [PDF]
, 2007 summary:In this paper we study the set of copulas for which both a horizontal section and a vertical section have been given. We give a general construction for copulas of this type and we provide the lower and upper copulas with these sections ...

Relations among univariate aging, bivariate aging and dependence for exchangeable lifetimes [PDF]
For a couple of lifetimes (X1,X2) with an exchangeable joint survival function , attention is focused on notions of bivariate aging that can be described in terms of properties of the level curves of .
