| Abstract | |
Can one compute the exponential rate of growth of the {*}-codimensions of a PI-algebra with involution {*} over a field of characteristic zero? It was shown in {[}2] that any such algebra A has the same {*}-identities as the Grassmann envelope of a finite dimensional superalgebra with superinvolution B. Here, by exploiting this result we are able to provide an exact estimate of the exponential rate of growth exp{*} (A) of any PI-algebra A with involution. It turns out that exp{*} (A) is an integer and, in case the base field is algebraically closed, it coincides with the dimension of an admissible subalgebra of maximal dimension of B.
