The Euler characteristic has the following property: for a fiber bundle F->E->B, we have χ(E)=χ(F)χ(B). Restricting the class of fibrations yields a broader family of multiplicative genera. In this way Landweber–Stong elliptic genus arise. Within a unified framework, I will present the following generalizations:
- Hirzebruch’s level N elliptic genus,
- the universal elliptic genus (as considered by Höhn or Krichever).
