Kahler forms on Cohen Macaulay spaces
Hi.
Can anyone me say if this two questions:
1) For $n$-dimensional $X$ Cohen-Macaulay complex space, is there true that the sheaf of top degre homolorphic forms $\Omega^{n}_{X}$ without torsion?
2) For $f:X\rightarrow S$ Cohen-Macaulay morphism of reduced complex spaces, is there tue that $\Omega^{n}_{X/S}$ is without torsion on $X$?
have a positive answers.
I think that the answers must be negative but i dont know how to prove it...
In fact, if it is true then the "fundamental class morphism" would be injectiv!
Thank you.
