Obtaining Homology Groups in Binary 2D Images Using P Systems
(IEEE Computer Society, 2009)
Membrane Computing is a new paradigms inspired from cellular communication. We use in this paper the computational devices called P systems to calculate in a general maximally parallel manner the homology groups of ...

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 ...

Computing “Small” 1–Homological Models for Commutative Differential Graded Algebras
(Springer, 2000)
We use homological perturbation machinery specific for the algebra category [13] to give an algorithm for computing the differential structure of a small 1– homological model for commutative differential graded algebras ...

“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[símbolo de infinito]–coalgebra structures on the Zp-homology of Eilenberg-Mac Lane spaces
(Universidad de Cantabria, 2004)
We study here the A(1)-coalgebra structure of the homology H (K( , n);Zp) of an Eilenberg-Mac Lane space K( , n), where is a finitely generated abelian group and n is a positive integer. Using diverse techniques of ...
