In mathematics a nonabelian cohomology is any cohomology with coefficients in a nonabelian group a sheaf of nonabelian groups or even in a topological space If homology is thought of as the abelianization of homotopy cf Hurewicz theorem then the nonabelian cohomology may be thought of as a dual of homotopy groups Nonabelian Poincare duality editThis section needs expansion You can help by adding to it October 2013 See Nonabelian Poincare Duality Lecture 8 See also editStacks Group cohomologyReferences editToen B Stacks and non abelian cohomology PDF Archived from the original PDF on January 14 2014 Lurie Jacob 2009 Higher Topos Theory Annals of Mathematics Studies Vol 170 Princeton NJ Princeton University Press ISBN 978 0 691 14049 0 Zbl 1175 18001 nbsp This topology related article is a stub You can help Wikipedia by expanding it vte Retrieved from https en wikipedia org w index php title Nonabelian cohomology amp oldid 918893810, wikipedia, wiki, book, books, library,
