We prove over some local commutative noetherian rings that the sequence of Betti numbers of every finitely generated module is either eventually constant or has termwise exponential growth.

We compute the rational Betti numbers of the configuration space C k (M) of k points in an evendimensional orientable closed manifold M and prove that these numbers depend only on the rational cohomology algebra of the manifold. We give also a formula for the Euler-PoincarΓ© characteristic of C k (M)
