Résumé

In this paper we study the parameterized complexity of approximating the parameterized counting problems contained in the class $# W [P]$ , the parameterized analogue of $# P$ . We prove a parameterized analogue of a famous theorem of Stockmeyer claiming that approximate counting belongs to the second level of the polynomial hierarchy.
