Abstract.
"Möbius functions" appear in different forms in
combinatorics. The algebraic setting for the "Möbius
inversion" is the "incidence algebra". We survey a general
theory of incidence algebras, and indicate several applications.
The paper has been finally published as the book
"Möbius functions, incidence algebras and power series
representations",
