Abstract: | Using some conjectures on the mean-value of generalized numbers, limit theorems in the sense of the weak convergence of probability measures for the Dirichlet series related to the Euler function are proved. Also, the limit measure is studied. Partially supported by the Lithuanian State Science and Studies Foundation. Vilnius University, Naugarduko 24, 2006 Vilnius, Lithuania: Šiauliai University, P.
