We can represent W by the integral......
We represent A as a quotient space of X by sending the point...... to...... [Not: “We present'']
We shall then show that this f can be represented in the form (5).
In particular, integral curves evolve continuously, and we should seek to represent them using a measure which reflects this continuity in some way.
This accords with the intuition that as we pass down the coding tree, we find out more and more detailed information about the ordering actually represented.
It turns out that A, B and C all belong to the same class, which we represent by the symbol P2.
We shall use the symbol ∩ to represent intersection.
We use upper case letters to represent inverses of generators.
