On Some Explicit Results for the Balanced Generalised Polya Urn
The article describes an explicit approach to urn models of the balanced generalised Polya type (with two types of balls). The treatment starts obtaining the difference equations, describing the discrete time behaviour of the expectation value and of the variance of the extraction probability for a given type of balls. The explicit solutions of such difference equations have been found in terms of Gamma and Psi (Digamma) functions
