To begin with, we note that there’s no functor that does: R 7! b Re=W where R is a at lift of R to W. The following deformation theory result says that we can nde at least one lift, but they are most de nitely not unique. Lemma 1.0.1.

Most notably, we reprove Berthelot's comparison result without using pd-stratifications, linearisations, and pd-differential operators. eagan ymca parents night out
