Subject: Re: Actions of monoidal functors  [was Re: Arens product]

Dear Jeff

"Monoid" and "object on which a monoid acts" make sense in any
multicategory. A monoidal functor is a monoid in the convolution
multicategory [V,W] of functors from V to W. The T of which you speak
is an object on which M acts in [V,W].

Regards,
Ross
