Abstract

We construct a canonical family of even periodic E-ring spectra, with exactly one member of the family for every prime p and chromatic height n. At height 1 our construction is due to Snaith, who built complex K-theory from CP. At height 2 we replace CP with a p-local retract of BU〈6〉, producing a new theory that orients elliptic, but not generic, height 2 Morava E-theories. In general our construction exhibits a kind of redshift, whereby BP〈n−1〉 is used to produce a height n theory. A familiar sequence of Bocksteins, studied by Tamanoi, Ravenel, Wilson, and Yagita, relates the K(n)-localization of our height n ring to work of Peterson and Westerland building EnhSG± from K(Z,n+1).
