But..is really so easy? (Möbius inversion), let be F(x) and G(x) functions(adsbygoogle = window.adsbygoogle || []).push({});

[tex] F(x)= G(ax)+G(2ax)+G(3ax)+............... [/tex]

for n=,1,2,3,4,5,............ a is a fixed real number. then

[tex] G(ax)= \sum_{n=1}^{\infty}\mu (x) F(nx) [/tex]

is seems too easy for me, to be true.
