*: The theory of conjunctively tensed copulae will be developed and stated with more precision in the following section.
*: This paper explores the position of the copula in the development of the verb system in second language acquisition of Italian.
*: The present study focuses on the acquisition of a specific verbal element, namely the copula, in predicative constructions in a cross-linguistic perspective (English, German, Croatian).

*: Copulas provide an example of the haphazard evolution of quantitative finance. The key result is Sklars theorem, which says that one can characterize any multivariate probability distribution by its copula (which specifies the correlation structure) and its marginal distributions (the conditional one dimensional distributions). Thus one can create multivariate distributions by mixing and matching copulas and marginal distributions.
*: A recently developed flexible method is provided by hierarchical Archimedean copulae (HAC).
