Question: is it true that a functorial, $0$-connected, homotopy
associative $H$-space with
$H$-unit is naturally weakly equivalent to a functorial $H$-group?
To formulate the question precisely:
Let I be a small category; write $C$ for the category of functors from
I to pointed simplicial sets. An $H$-associative $H$-unital funtorial
$H$-space is an object $H$ of $C$ with an operation $+:H\times H\to
H$ wich is associative up to natural homotopy
and is such that $*$ is an identity up to natural homotopy. If in
addition there is a natural
map $H\to H$ which is naturally a homotopy inverse for the operation
$+$, we call $H$
a functorial $H$-group. Assuming $H_i$ is $0$-connected for all $i\in
I$, does it follow that there exists a functorial $H$-group $H'$ and a
string of weak equivalences of $H$-objects connecting $H$ with $H'$
each of which preserves the operation up to natural homotopy?
