SUMMARY:Khaydar Nurligareev (LIPN\, Université Paris 13): Asymptotics for 
 the probability of labeled objects to be irreducible
DESCRIPTION:Khaydar Nurligareev: There are a number of combinatorial struct
 ures that admit\, in a broad sense\, a notion of irreducibility\, includin
 g connected graphs and surfaces\, irreducible tournaments\, indecomposable
  permutations and so on. We are interested in the probability that a rando
 m labeled object is irreducible\, as its size tends to infinity. We will s
 how that for some classes of objects it is possible to obtain the asymptot
 ics for these probabilities in a common manner and that asymptotic coeffic
 ient have a combinatorial meaning. More precisely\, it is so when the cons
 idered combinatorial class can be described as a set or a sequence of the 
 corresponding irreducible class\, and its counting sequence grows sufficie
 ntly fast. Moreover\, we will show how to obtain the asymptotic probabilit
 y that a random labeled object has a given number of irreducible component
 s\, and we will indicate the combinatorial meaning of the coefficients inv
 olved in the asymptotic expansions.\nThis is an ongoing work joint with Th
 ierry Monteil.\n\nKhaydar Nurligareev nous parlera des contages combinatoi
 res des différents objets\, notamment\, des surfaces à petits carreaux.\
