An algorithm for computing the first homology groups of CDGAs with linear differential
(Research Institute for Symbolic Computation, 1999)
We design here a primary platform for computing the basic homological information of Commutative Differential Graded Algebras (brie y, CDGAs), endowed with linear differential. All the algorithms have been implemented ...

Computing Cocycles on Simplicial Complexes
(Springer, 1999)
In this note, working in the context of simplicial sets [17], we give a detailed study of the complexity for computing chain level Steenrod squares [20, 21], in terms of the number of face operators required. This analysis ...

A combinatorial method for computing Steenrod squares
(Elsevier, 1999)
We present here a combinatorial method for computing Steenrod squares of a simplicial set X. This method is essentially based on the determination of explicit formulae for the component morphisms of a higher diagonal ...
