Subject: Limits in REL
Date: Thu, 3 Jul 2014 11:57:18 +0100	[thread overview]
Message-ID: <E1X2x7j-00012x-5O@mlist.mta.ca> (raw)

Hi all

What is known about limits in REL , the (bi)category of sets and relations?
I know there are biproducts; are there equalisers?

And what about SPAN(C) or REL(C), spans and relations over a suitable
category  C ?

Thanks a lot in advance,
Ondrej
