Hello,
This is a followup question to my other question
about topoi and intuistionistic logic. On page 350,
Lawvere is talking about logical operations (in
a Heyting algebra I think??). In particular I
having trouble understanding the narrative on the
implication operation "=>" in the sense
1) I don't understand what <alpha, beta>. (e.g.
is alpha meant to be an
element: alpha:1->omega?)
2) also what alpha "subset" beta is!
Please help me.
Thanks and regards, Bill Halchin
