| Oct 2, 2010 at 17:24 | comment | added | Harry Gindi | Is that first construction in Theo's question related to Quillen's construction $M\mapsto R\oplus M \to R$ for $M$ an $R$-module (R a commutative $A$-algebra), which sends an R-module to a nilpotent thickening (also an $A$-algebra) of $R$ with kernel isomorphic to M. | |
