comment $A \otimes^L_B C$ computing the derived fiber product of schemes
What do you mean by the "codimension of A"? Usually codimension is defined for a subscheme. Also - in this case, which vector bundle on $\mathfrak{g}$ will you pick?

comment $A \otimes^L_B C$ computing the derived fiber product of schemes
I understand what a flat module over a ring is but -- given a map $A \rightarrow B$ what does it mean for a sheaf of DG-algebras on $A$ to be flat over $B$? Thanks.

Ah okay. But what is the precise definition of a "complete intersection subscheme"? Hartshorne doesn't have a definition either.

comment $A \otimes^L_B C$ computing the derived fiber product of schemes
Thanks - that makes sense! But for the example, $A=\tilde{\mathfrak{g}} \rightarrow \mathfrak{g}=B$ -- what does the corresponding sheaf of dg-algebras (ie. the Koszul complex) look like?
