Journal of Symbolic Computation, 40 (4-5), 1208-1224.http://hdl.handle.net/11441/30797This paper offers an algorithmic solution to the problem of obtaining “economical” formulae for some maps in Simplicial Topology, having, in principle, a high computational cost in their evaluation. In particular, maps of this kind are used for defining cohomology operations at the cochain level. As an example, we obtain explicit combinatorial descriptions of Steenrod View the MathML sourcekth powers exclusively in terms of face operators.application/pdfengAtribución-NoComercial-CompartirIgual 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-sa/4.0/Cohomology operationsSimplicial setsFace and degeneracy operatorsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/doi:10.1016/j.jsc.2004.04.008
