Re: [math-fun] binary operation seeks symbol, name

=Erich Friedman i rather like smin and smax. if nothing else, they are fun to say.....

=Joerg Arndt minp (MIN or Previous) maxn (MAX or Next) Not so fun to say but sufficiently suggestive.

So, maybe a hybrid? pmin (Predecessor or MINimum) smax (Successor or MAXimum) with natural duals smin and pmax

=James Propp I need symbols

Why? Are you expecting to write a lot of "algebra" with these as binary infix operators? If not, four letters seems reasonably terse and perhaps more scrutable. Curious: they easily generalize to more than two arguments, but not fewer. They almost seem like parts for a Turing machine...
