To Joe Lipman
These are notes to my talk at Lipman's birthday conference. Some
details have appeared in [A1, A2]. The rest hopefully will someday.
1. Differential Forms
Let X be a smooth complete variety over C. Then
as a consequence of Hodge theory + GAGA:
Hi
(Xan

(X,
X) =
a+b=i

If X is complete but singular, then both these iso-
