Some new characterizations and properties of quasi-copulas
In this paper we characterize the concept of quasi-copula in three different ways: as a special subclass of aggregation operators, in terms of its associated volume and-for the bivariate case-in terms of non-increasing tracks on [0, 1](2). We also provide sufficient conditions and new properties for quasi-copulas. (C) 2008 Elsevier B.V. All rights reserved.
