Codice 16/2009 Titolo A functional equation whose unknown is P ([0, 1]) valued Data 2009-05-20 Autore/i Aletti, Giacomo; May, Caterina; Secchi, Piercesare Link Download full text Abstract We study a functional equation whose unknown maps a euclidean space into the space of probability distributions on [0,1]. We prove existence and uniqueness of its solution under suitable regularity and boundary conditions and we characterize solutions that are diffuse on [0,1]. A canonical solution is obtained by means of a Randomly Reinforced Urn with different reinforcement distributions having equal means.
