| Nov 2, 2012 at 7:07 | comment | added | Neil Strickland | Here's a point of terminology that will help you find references: an $H_\infty$ structure on $\bigvee_{k\in d\mathbb{Z}}\Sigma^kE$ is essentially what is called an $H^d_\infty$ structure in the $H_\infty$ book (Springer LNM 1176). Of course $H_\infty$ is weaker than $E_\infty$ but this is a start. | |
