Subject: Elementary concepts of map objects
Date: Fri, 08 May 2009 10:41:02 -0700 [thread overview]
Message-ID: <E1M3r6C-00028K-N6@mailserv.mta.ca> (raw)
In light of the recent discussion here about
the "horizontal line notation", I've returned
to the introduction to map objects in L. & S.,
_Conceptual Mathematics_. This statement is
in the rectangle at the top of page 314.
( Script.ChangeFont Courier8 )
T e X ----> Y
T x Y ----> Y induces -------------
T x X ----> Y
Evaluation map e induces a "correspondence".
Is this horizontal line an implication or
an equivalence or a map or a bijection?
"Induces" seems plausible but exactly what
is meant?
Thanks, ... Peter E.
