Una rassegna di risultati asintotici per modelli d'urna rinforzati stocasticamente e loro applicazioni, dott.ssa Irene CRIMALDI, Istituto di Alti Studi, Lucca
Abstract: Urn models are a very popular topic because of their applications in various fields: sequential clinical trials, biology, economics and computer science. A large number of "replacement policies" has been considered and studied by many authors, from different points of view and by means of different methods. As regards asymptotics in urn models, there is not a unique reference framework. Rather, there are many (ingenious) disjoint ideas, one for each class of problems. Well known examples are martingale methods, exchangeability, branching processes and so on. We will illustrate some recent convergence results for two kinds of randomly reinforced urn models: the first one is a multicolor randomly reinforced Polya urn and the second one is a "Poisson-Dirichlet type" sequence. For reader's convenience we will review the known asymptotic results for the classical multicolor Polya urn and the classical Poisson-Dirichlet sequence. We will also discuss a recent application of these results to analyze complex networks. -

Construction of Nordsieck methods with quadratic stability function, dott. Michal BRAS, University of Science and Technology, Kraków, Poland
Abstract: General linear methods are a wide class of numerical methods for solving ordinary differential systems which includes many classical methods, such as for example Runge-Kutta or linear multistep methods. We concentrate on construction of methods in Nordsieck form with the so-called quadratic stability (QS). We illustrate inherent quadratic stability conditions and describe the search for implicit and explicit methods with QS and the optimal properties of stability and efficiency.

Algorithms to identify some classes of groups defined in terms of normality, permutability, and Sylow permutability, prof. Ramon ESTEBAN-ROMERO, Università di Valencia
Abstract: We describe some algorithms which allow us to identify permutable and S-permutable subgroups and whether a group is a T-group, a PT-group, or a PST-group (that is, normality, permutability, or Sylow permutability are transitive relations in the group). These algorithms have been implemented in GAP.
