Let A Q be the group of complex unit roots of an integer order \( Q \geqslant 2 \). Let \( {\xi_p}\left( {p \in \mathcal{P}} \right) \) be independent random variables distributed uniformly on the set A Q , where \( \mathcal{P} \)is the set of primes. Let f be a completely multiplicative function defined on \( \mathcal{P} \) by f(p) = ξ p . We investigate the summatory function of f(n) and the density of those n for which f(n + j) = κ j (j = 0, …, t), where κ j ∈ A Q . 相似文献

This paper shows that any completely additive complex valued function over a principal configuration in the complex plane, having constant values in some discs, is the identically zero function. In other words, there exists no non-trivial completely additive complex valued function over a principal configuration in $\mathbb{C}$ which assumes constant values in some domain. 相似文献

Two kinds of spaces of harmonic functions defined on m-dimensional domains are considered. In the first case, the spherical domain is a m-dimensional ball Br in the second case Br is replaced by Br1,r2:=Br2Br1. In both cases, several inner products are considered and Hilbert space properties are proved. The reproducing kernel functions of these spaces and hence some new representations for harmonic functions are also obtained 相似文献

Suppose that is a relatively countably compact subset of B1(X), the space of Baire I functions over a K-analytic space X equipped with the pointwise convergence topology. It is proved that (1) the closure of is a strongly countably compact Frechét-Urysohn space; (2) if is 1 -compact, is a bicompactum; (3) if X is a paracompact space, the closure of is a bicompactum.Translated from Matematicheskie Zametki, Vol. 52, No. 3, pp. 108–116, September, 1992. 相似文献

Summary This paper studies arithmetical functions that are prime-independent and multiplicative. Firstly, it establishes necessary
and sufficient conditions for such functions to possess simple formulae relating them to the zeta function. Then it investigates
asymptotic average-values and moments of such functions. The results apply to functions of ideals in algebraic numbers fields,
or of isomorphism classes in certain categories, as well as to functions of positive integers.
