Dear All,
I have been trying to compare the simplicially enriched
category/Segal-category approach to weak categories and the
dg-category/$A_\infty$-category approach coming from derived categories
etc. It is clear that there is a cobar construction leading from a
dg-cocategory to a dg-category and results on twisting cochains also go
across with no difficulty. I am therefore surprised that I cannot find
an explicit reference for this in the literature (probably I have not
loked in the right place as it is in an `overlap' area!). Can anyone
help with some good references?
Also has anyone given a good interpretation of the twisting cochains and
the twisted tensor of modules in this setting. I know of the usual
interpretations. Perhaps someone who knows the string theoretic links
may have an idea.
Thanks,
Tim Porter
