 Nov 16 comment Functions over $R$ such that $f(xy) = f(x)f(y)$ Oh yes, I forgot all about the fact that $(xy)^n = x^n y^n$. So I guess the answer to the first question is "yes", but my second question remains.

I'd imagine the 'unit interval' refers to the set [0,1], but you wouldn't say that the number 0.3 is a "unit interval number" in the same way that you might say that 2/3 is a "rational number". It's not entirely clear from the question but I think it's asking for a term to describe any number in the set, not to describe the set itself. Aug 12 comment Interesting properties of ternary relations? Okay. That is interesting but it's not the type of property that I was after -- I want properties expressible in first order logic (+ identity). Aug 7 comment Interesting properties of ternary relations? I'd be interested to hear some of those properties. The only one I can think of (off the top of my head) is R(x,y,z) <-> R(y,x,z). Aug 3 comment Interesting properties of ternary relations? I'm now sure why you put that as a comment rather than as an answer. Aug 3 asked Interesting properties of ternary relations? Aug 3 comment How do the Properties of Relations work? Asymmetric does not mean "not symmetric" in the context of binary relations. The relation "x is a factor of y" is not symmetric (since 3 is a factor of 6 and not vice versa). But it is not asymmetric either by any standard definition of asymmetry. Jul 30 accepted Characterising functions$f$that can be written as$f = g \circ g\$?
