Description des Champs Aleatoires par des Probabilites Conditionelles Uniponctuelles
Mercredi 02 novembre 2005 - 10h30 -
The problem of description of random fields by means of conditional probabilities in singletones is considered. The description of specifications and of random fields
by means of n-specifications (consistent systems of probability distributions in volumes of cardinality bounded by n with infinite boundary conditions) is established
under different positivity conditions (from strict positivity up to very weak positivity). Particular attention is paid to the most important case n=1 which correspondes
to singletones and requires special considerations.
