Résumé : I will explain recent developments on Virasoro irregular conformal blocks, which are defined as expectation values of vertex operators of Virasoro algebra. As an application, I will show that the tau function of the fifth Painleve equation is expressed in terms of three-points irregular conformal blocks of rank one.
