Some characterizations of specially multiplicative functions [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
A multiplicative function f is said to be specially multiplicative if there is a completely multiplicative function fA such that f(m)f(n)=∑d|(m,n)f(mn/d2)fA(d) for all m and n.

Characterizing completely multiplicative functions by generalized Möbius functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Using the generalized Möbius functions, μα, first introduced by Hsu (1995), two characterizations of completely multiplicative functions are given; save a minor condition they read (μαf)−1=μ−αf and fα=μ−αf.

A note on $(a,b)$-Fibonacci sequences and specially multiplicative arithmetic functions [PDF]

open access: yesMathematica Bohemica
A specially multiplicative arithmetic function is the Dirichlet convolution of two completely multiplicative arithmetic functions. The aim of this paper is to prove explicitly that two mathematical objects, namely $(a,b)$-Fibonacci sequences and ...

Multiplicative Square Functions

open access: yesRevista Matemática Iberoamericana, 2004
We study regularity properties of a positive measure in the euclidean space in terms of two square functions which are the multiplicative analogues of the usual martingale square function and of the Lusin area function of a harmonic function.

Completely multiplicative functions arising from simple operations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Given two multiplicative arithmetic functions, various conditions for their convolution, powers, and logarithms to be completely multiplicative, based on values at the primes, are derived together with their applications.

Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]

open access: yes, 2000
Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).

On a Multiplicative Partition Function [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2000
Let $D(s)=\sum^\infty_{m=1}a_mm^{-s}$ be the Dirichlet series generated by the infinite product $\prod^\infty_{k=2}(1-k^{-s})$. The value of $a_m$ for squarefree integers $m$ with $n$ prime factors depends only on the number $n$, and we let $f(n)$ denote this value.

open access: yesNotes on Number Theory and Discrete Mathematics
In the paper, an extension of the well-known Jordan's totient function and generalized Dedekind psi-function are proposed and some properties of theirs are studied.
