Preliminaries: relations and closures


I think everything I write in the preliminaries can be found in Birkhoff, "Lattice theory". Can anyone check? (I don't think I have easy access to a copy.

In particular, I think xR was written x^{\leftarrow}, with the relation R being implicit.

If so, we should add a reference to that.

The refinement calculus people use the relation in the reverse order: what I write \langle R\rangle, they write \langle R^\sim\rangle. (The same is true of [R].) I find it confusing, and since this is hardly "standard" notation one way or the other, I don't think this is important...

Phase semantics


I put the remark

Some people say that this idea of orthogonality was implicitly present in Tait's proof of strong normalisation. More recently, Jean-Louis Krivine and Alexandre Miquel have used the idea explicitly to do realisability...

at the end of the subsection "multiplicative connectives".

Has anybody heard the same about Tait proof and biorthogonal?
