Primitive elements of a tensor product of bialgebras
Well first when we restrict to the case when $A, B$ are filtered (see Bourbaki for example), in this case $\log_{*}$ always converges at $Id$ (as $Id=e+I_+$, $e$ being the unit for the convolution, it …

Cocommutativity, comultiplication and coalgebra maps
In short, this property is true only in the context of counital coalgebras and NOT otherwise. … Remark : It is transparent in terms of identities that the property is true for coassociative coalgebras with counits. …
