Abstrakt EN: The pseudointersection number and the almost disjointness number of quotients algebras P(N)/I are studied for some analytic ideals, in particular for the van der Waerden ideal W. We prove that the pseudointersection number of P(N)/W coincides with the standard pseudointersection number p and the almost disjointness number of P(N)/W is less or equal the standard almost disjointness number a.
