and
nonabelian homological algebra
The Eilenberg-Moore spectral sequence is a spectral sequence for the singular homology of product topological spaces which generalizes the Künneth theorem in two ways
it applies without assumption on vanishing of Tor-groups;
it generalizes from product topological spaces to fiber products of fibrations and to products over group actions.
