## Idea

The traditional Chern character on complex K-theory happens to be a map from complex oriented cohomology theory of chromatic level 1 to one of chromatic level 0 (ordinary cohomology).

More generally, one may ask for higher chromatic Chern characters that map a generalized cohomology theory of some chromatic level to another of some other level.

This has been considered for
