Abstract:
In the paper for an arbitrary basic monoid
${M(\mathbb{P}(q))}$ of type
$q$ the inverse problem is solved, that is, finding the asymptotics for the distribution function of the elements of the monoid
${M(\mathbb{P}(q))}$, based on the asymptotics of the distribution of pseudo-prime numbers
$\mathbb{P}(q)$ of type
$q$.
To solve this problem, we consider two homomorphisms of the main monoid
${M(\mathbb{P}(q))}$ of type
$q$ and the distribution problem reduces to the additive Ingham problem.
It is shown that the concept of power density does not work for this class of monoids. A new concept of
$C$ logarithmic
$\theta$-power density is introduced.
It is shown that any monoid
${M(\mathbb{P}(q))}$ for a sequence of pseudo-simple numbers
$\mathbb{P}(q)$ of type
$q$ has upper and lower bounds for the element distribution function of the main monoid
${M(\mathbb{P}(q))}$ of type
$q$.
It is shown that if
$C$ is a logarithmic
$\theta$-power density for the main monoid
${M(\mathbb{P}(q))}$ of the type
$q$ exists, then
$\theta=\frac{1}{2}$ and for the constant
$C$ the inequalities are valid $ \pi\sqrt{\frac{1}{3\ln q}}\le C\le \pi\sqrt{\frac{2}{3\ln q}}. $
The results obtained are similar to those previously obtained by the authors when solving the inverse problem for monoids generated by an arbitrary exponential sequence of primes of type
$q$.
For basic monoids
${M(\mathbb{P}(q))}$ of the type
$q$, the question remains open about the existence of a
$C$ logarithmic
$\frac{1}{2}$-power density and the value of the constant
$C$.
