Commutativity conditions for truncated Brown-Peterson spectra of height 2
Commutativity conditions for truncated Brown-Peterson spectra of height 2
An algebraic criterion, in terms of closure under power operations, is determined for the existence and uniqueness of generalized truncated BrownāPeterson spectra of height 2 as Eā-ring spectra. The criterion is checked for an example at the prime 2 derived from the universal elliptic curve equipped with a level Ī1(3) ā¦
