An example in combinatorial cohomology
(Universidad de La Rioja, 2001)
Steenrod cohomology operations are algebraic tools for distinguishing non–homeomorphic topological spaces. In this paper, starting off from the general method developed in [4] for Steenrod squares and Steenrod reduced ...

“Coalgebra” Structures on 1-Homological Models for Commutative Differential Graded Algebras
(Springer, 2001)
In [3] “small” 1-homological model H of a commutative differential graded algebra is described. Homological Perturbation Theory (HPT) [7-9] provides an explicit description of an A∞-coalgebra structure (Δ1,Δ2,Δ3,...) of ...

A computational approach to free divisors and logarithmic D-modules
(Universidad de La Rioja, Departamento de Matemáticas y Computación, 2001)
We apply algorithmic techniques for comparing some D-modules associated to a kind of divisors in Cn.
