Extended teisi in Ab

Sjoerd Crans, CTRC Seminar 8 February 2000

This talk extended my talk `Teisi in Ab' at the OctoberFest, giving the details of extending the principal result, that teisi in Ab are omega

-groupoids, as far as possible. I proved that for an omega

-category in Ab, an extra operation of arity a diagrammatic globular set which has strict unit axioms is trivial. Thus, the principal result also holds for normalized weak omega

-categories in Ab.

See section 6 of the paper ``Teisi in Ab''.

Previous and next abstract.
