The real-oriented cohomology theory-version of Morava E-theory.

## References

ER-theory was constructed in

• Igor Kriz, Real-oriented homotopy theory and an analogue of the Adams-Novikov spectral sequence, Topology 40 (2001) 317-399 (pdf)

based on Araki’s discussion of BPR-theory.

The orientation in generalized cohomology for $ER$-theory by $w_4$-structure is discussed in

Some relations to versions of tmf are discussed in
