On the Jacobian criterion of formal smoothness.

Publicacions Matemàtiques


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


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


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.
