A P ólya urn is a stochastic process that describes the composition of an urn that contains balls of different colours. The set of colours is usually a finite set {1, ... , d}. At each discrete-time step, one draws a ball uniformly at random in the urn (let c be its colour), and replace it in the urn together with R(c,i) balls of colour i, for all i = 1, ... , d. In this talk, I will present a generalisation of this model to an infinite, and potentially uncountable set of colours. In this new framework, the composition of the urn is a measure (possibly non-atomic) on a Polish space.
