| Feb 2 at 13:50 | comment | added | user509184 | If I remember correctly, the EKMM book uses the term "$MU$-algebra" to mean an $A_\infty$ $MU$-algebra, while "associative $MU$-ring spectrum" is used in that book to mean something weaker, where associativity is only required up to homotopy. Something similar for "commutative $MU$-ring spectrum" vs. "commutative $MU$-algebra". The results V.2.6 and V.3.2 you refer to are only claiming you get $MU$-ring spectrum structures on $BP$, not $MU$-algebra structures--not quite what you wrote in your question. I think that's where your confusion is coming from. | |
