Summary
There are some inequalities concerning the module of derivations of a local ring which are true in characteristic0 and false in general in characteristic p≠0 (as it is well known); in the present paper we prove that such inequalities in char. p are true for the module of integrable derivations. Moreover we give some sufficient conditions for an associated prime ideal to be differentiable in char. p.
