Re: 2-categorical monad functor lifting

["Francisco Marmolejo (314)" <quico@matem.unam.mx>]

Dear Steve,

you may want to check

Coherence for pseudodistributive laws revisited
F. Marmolejo and R.J. Wood
Theory and Applications of Categories, Vol. 20, No. 6, 2008, pp. 74–84.

and the bibliography there-in for the pseudo case (and for pseudomonads). 
The standard reference for the 1-categorical case must surely be

The formal theory of monads
R. Street
J. Pure Appl. Algebra 2 (1972)
