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.

The general structure of inverse polynomial modules

Sangwon Park (2001)

Czechoslovak Mathematical Journal

Similarity:

In this paper we compute injective, projective and flat dimensions of inverse polynomial modules as R [ x ] -modules. We also generalize Hom and Ext functors of inverse polynomial modules to any submonoid but we show Tor functor of inverse polynomial modules can be generalized only for a symmetric submonoid.

Almost-flat modules

Simion Breaz (2003)

Czechoslovak Mathematical Journal

Similarity:

We present general properties for almost-flat modules and we prove that a self-small right module is almost flat as a left module over its endomorphism ring if and only if the class of g -static modules is closed under the kernels.
