Crossed complexes and higher homotopy groupoids as noncommutative tools for higher dimensional local-to-global problems. (English) Zbl 1214.18014

Hazewinkel, M. (ed.), Handbook of algebra. Volume 6. Amsterdam: Elsevier/North-Holland (ISBN 978-0-444-53257-2/hbk). Handbook of Algebra 6, 83-124 (2009).
The author surveys and explains the origins of results obtained by himself, P. J. Higgins and others over the years 1974–2008 in basic algebraic topology on the border between homology and homotopy, using crossed complexes, rather than chain complexes, as a fundamental notion.
