Let A be an associative PI-algebra over a field F of characteristic zero. By studying the exponential behavior of the sequence of codimensions [c n (A)] of A, we prove that Inv(A)=lim n Γ„ n c n (A) always exists and is an integer. We also give an explicit way for computing such integer: let B be a f
