For the disjoint union, I don't like \amalg and \coprod very much. So, I did all my best to create a \varamalg with this code:




$A\varamalg B=A\cup B$


And I get:

enter image description here

Well, not bad for me. I used \smallsetminus because the ends are rounded.

But now, I'm not able to create \varcoprod. Could you help me?

So by \varcoprod you're just after an operator-type \varamalg? If not, could you explain more what \varcoprod should look like, and how you plan on using it? – Werner Mar 18 '14 at 17:14
