Multiplicative structures on Brown-Peterson spectra at odd primes

Abstract: We show that the odd-primary Brown-Peterson spectrum does not admit the structure of an E_{2(p^2+2)} ring spectrum and that there can be no map MU–>BP of E_{2p+3} ring spectra at any prime. This extends results of Lawson at the prime 2.
