Transform of Möbius

the transforms of Möbius should not be confused with the Transformation of Möbius.

---- The transformed of Möbius of the function F definite on the strictly positive entireties, is the function Tf definite as follows:
(Tf) (N) = \ sum_ {D \ mid N} F (d) \ driven (n/d)= \ sum_ {D \ mid N} F (n/d) \ driven (d),

where μ is the Fonction of Möbius.

(The notation D | N means that D divides N .)

This function is thus named in homage to August Ferdinand Möbius.

The reverse transformation T-1f is given by

(T^ {- 1} F) (N) = \ sum_ {D \ mid N} F (d)
