Two results on the logarithmic cotangent complex
Jesús Conde-Lago, Javier Majadas
In this paper we give two results on the logarithmic cotangent complex: we construct a logarithmic analogues to the complex of Lichtenbaum and Schlessinger and to Quillen's fundame…

Homological characterization of regularity in Logarithmic Algebraic Geometry
Jesús Conde-Lago, Javier Majadas
We characterize K. Kato's log regularity in terms of vanishing of (co)homology of the logarithmic cotangent complex.

Cohen-Macaulay, Gorenstein, Complete intersection and regular defect for the tensor product of algebras
S. Bouchiba, J. Conde-Lago, J. Majadas
This paper main goal is to measure the defect of Cohen-Macaulayness, Gorensteiness, complete intersection and regularity for the tensor product of algebras over a ring. For this sa…

A short proof of smooth implies flat
Jesús Conde-Lago
Proofs that a smooth morphism is flat available in the literature are long and difficult. We give a short proof of this fact.
