Abstract
The paper continues research on a new class of Dirichlet series — zeta functions of monoids of natural numbers. The inverse Dirichlet series for zeta functions of monoids of natural numbers with unique factorization into prime elements and for zeta-functions of sets of prime elements of monoids with unique factorization into prime elements are studied. For any β > 1 examples of Dirichlet series with an abscissa of absolute convergence σ = are constructed. For any natural β > 1 examples of a pair of zeta functions ζ(B|α) and ζ(A B, β |α ) with the equality σ AB,β = σB/ β are constructed. Various examples of monoids and corresponding zeta functions of monoids are considered. A number of properties of the zeta functions of monoids of natural numbers with unique factorization into prime factors are obtained. An explicit form of the inverse series to the zeta-function of the set of primes supplemented by one is found. An explicit form of the ratio of the Riemann zeta-function to the zeta-function of the set of primes supplemented by one is found. Nested sequences of monoids generated by primes are considered. For the zeta-functions of these monoids the nesting principle is formulated, which allows to transfer the results about the coefficients of one zeta-functions to the coefficients of other zeta-functions. In this paper the general form of all monoids of natural numbers with unique factorization into prime factors was described for the first time. In conclusion, topical problems for zeta-functions of monoids of natural numbers that require further study are considered.

Summary
В данной работе продолжаются исследования из работы [8] и сохраняются обозначения и определения из этой работы. Будем через P3,1 и P3,2 обозначать множество всех простых чисел вида 3n + 1 и 3n + 2, соответствено. В частности, в это множество псевдопростых чисел входят квадраты простых. Множество простых элементов P (M3,1,2,0) состоит из псевдопростых чисел вида p1p2, где p1, p2 — произвольные различные простые числа вида 3m + 2. Тогда для произвольного моноида M натуральных чисел с однозначным разложением на простые элементы справедливо равенство ζ(M |α) = P (M |α). Через k(x) будем обозначать количество различных канонических представлений числа x, тогда эйлерово произведение P (M |α) будет раскладываться в следующий ряд Дирихле. Равенство эйлерова произведения и дзета-функции моноида M равносильно однозначности разложения на простые элементы в этом моноиде. Цель данной статьи — описать моноиды натуральных чисел с однозначным разложением на простые элементы, изучить их свойства, дзета-функции этих моноидов натуральных чисел и найти их обратные ряды Дирихле
