A Multiple Sum Involving the Möbius Function
نویسنده
چکیده
We consider a multiple arithmetical sum involving the Möbius function which despite its elementary appearance is in fact of a highly intriguing nature. We establish an asymptotic formula for the quadruple case that raises the first genuinely non-trivial situation. This is a rework of an old unpublished note of ours. 2001 Mathematics Subject Classification: Primary 11A25; Secondary 11M06

Some Identities Involving Convolutions of Dirichlet Characters and the Möbius Function
In this paper we present some identities involving convolutions of Dirichlet characters and the Möbius function, which are related to a well known identity of Ramanujan, Hardy and Littlewood.
متن کاملRecursive Formulas Related to the Summation of the Möbius Function
For positive integers n, let μ(n) be the Möbius function, and M(n) its sum M(n) = Pn k=1 μ(k). We find some identities and recursive formulas for computing M(n); in particular, we present a two-parametric family of recursive formulas.

We derive some identities and inequalities concerning the Möbius function. Our main tool is phi functions for intervals of positive integers and their unions.
متن کاملModeling of temperature in friction stir welding of duplex stainless steel using multivariate lagrangian methods, linear extrapolation and multiple linear regression
In this study, the temperature in friction stir welding of duplex stainless steel has been investigated. At first, temperature estimation was modeled and estimated at different distances from the center of the stir zone by the multivariate Lagrangian function. Then, the linear extrapolation method and multiple linear regression method were used to estimate the temperature outside the range and ...
