Möbius function

Summary

The Möbius function μ\mu is an arithmetic function that is 00 on integers with a square factor greater than 11. On a squarefree integer, its value 11 or −1-1 depends on the parity of the number of prime factors. The definition of the Möbius function gives the precise form.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
