positive definite functions on a LCA-group with values in B(H)ors on a weakly complete Banach space X. Then the set of common eigenvectors of T(\^t) (\^t\(\in R^ n)\) is total if and only if the map \^t\(\mapsto T(\hat t)\) is weakly almost periodic. This result is applied to common eigenvectors of a finite family of commuting normal operators
