A.3.7 Depth

We compute the depth of the module of Kaehler differentials of the variety defined by the -minors of a generic symmetric We do this by computing the resolution over the polynomial ring. Then, by the Auslander-Buchsbaum formula, the depth is equal to the number of variables minus the length of a minimal resolution. This example was suggested by U. Vetter in order to check whether his bound could be improved.
