Subject: Horizontal line notation.
Date: Sun, 15 Mar 2009 07:35:37 -0800 [thread overview]
Message-ID: <E1LiyrZ-0001V6-Mj@mailserv.mta.ca> (raw)
Lawvere & Schanuel use a horizontal line
notation. Page 326 for example.
X --> 1^T
---------
TxX --> 1
This is unfamiliar. Does the line have a
name? How is it read? I'll guess either
"(X --> 1^T) is equivalent to (TxX --> 1)"
or
"(X --> 1^T) is isomorphic to (TxX --> 1)".
Thanks, ... Peter E.
