`Extension'  

Is there a dual term for this? (Don't say "co-lift"!) How about "extension"? I hadn't thought of that, and it might work [...] Actually, "extension" is the standard name for this categorical concept. Doesn't matter what the nature of h is. I can't rid myself of a feeling of discomfort about this. ... Jan 12 2005 by Marc Olschok - 11 messages - 5 authors

`Extension' (was: Dual of `lift'?)  

Not precisely as a term for the dual of lift, but rather as a catch-all term for both lifts and extensions. That's probably the only way not to risk being misunderstood.

Dual of `lift'?  

Is there a dual term for this? (Don't say "co-lift"!) How about "extension"?
