I've seen enough of your not so trivial proofs to think you're a professor
and noticing the topics to which you most often reply, I'd say your
speciality is set theory.

What do you consider difficult? Every GO space is a subspace of a linear
ordered space; complementation of the lattice of topogies; Rudin's
theorem that a space is compact, monotonically normal iff it's the
continuous image of some compact linear order space; space filling
curves; Brouwer's work?

Anyway, your replies have been enjoyable for their mathematical
excellence.
