The obtained results enable us to understand better the properties of these numbers and their asymptotic behavior. On the basis of these identities a simple proof of the Prime Number Theorem is represented.11 pages, revised versionNumber Theory11N05, 11A41On the properties of generalized harmonic and oscillatory numbers.
