Added a general characterization of all absolute pushouts, analogous to the one at absolute coequalizer.
]]>Nice, thanks! The notion of split coequalizer is the “case ” of a complete characterization of all absolute coequalizers that can be obtained by unraveling what it means for a coequalizer to be preserved by all representable functors. I presume there is a similar characterization of all absolute pushouts; have you looked into it?
]]>Just to say that I changed the page name to singular.
]]>This page proposes a notion of split pushout (of epimorphisms) that is then an absolute pushout “for equational reasons.”
