A compatible norm and a generalization of the *- product for copulas

Abstract

There are two parts in this thesis. In the first part, we define a norm and show that it is invariant under left and right *-products with invertible copulas. We then show that, restricted to the set of copulas, this norm preserves stochastic properties. As an application of the norm, we construct a measure of dependence which is invariant under Borel measurable bijective transformation. For the second part, we look into a generalization of the *-product, especially its definition, introduced by Durante, Klement and Quesada-Molina. We also derive some of its properties.
