On commutative FGI-Rings.
On ring derivations and quadratic functionals.
On some properties of pure morphisms of commutative rings.

On the Jacobian criterion of formal smoothness.
We give a short proof of the Jacobian criterion of formal smoothness using the Lichtenbaum-Schlessinger cotangent complex.
On the module of homomorphisms on finitely generated projective modules
On the Transitvity of regular differential Forms.
Outer automorphisms of endomorphism algebras
Commutative rings over which no endomorphism algebra has an outer automorphism are studied.
