Classification: 62N05, 60E15, 37L05 abstract: In previous papers, evolution of dependence and ageing, for vectors of non-negative random variables, have been separately considered. Some analogies between the two evolutions emerge however in those studies. In the present paper, we propose a unified approach, based on semigroup arguments, explaining the origin of such analogies and relations among properties of stochastic dependence and ageing. date: 2013 date_type: published publication: Kybernetika volume: 49 number: 1 publisher: Institute of Information Theory and Automation of the ASCR pagerange: 96-113 refereed: TRUE issn: 0023-5954 official_url: http://www.kybernetika.cz/content/2013/1/96 citation: Foschi, Rachele Hyper-dependence, hyper-ageing properties and analogies between them: a semigroup-based approach.
