rational homotopy theory (equivariant, stable, parametrized, equivariant & stable, parametrized & stable)
Examples of Sullivan models in rational homotopy theory:
The Pontrjagin character is the analog for KO--theory of what the Chern character is for KU--theory. Like the latter may be expressed as a series of Chern classes, so the Pontrjagin character is expressed as a series of Pontrjagin classes.
Equivalently, the Pontrjagin character is the Chern-Dold character on KO.
