Direct spectra of Bishop spaces and their limits
We apply fundamental notions of Bishop set theory (BST), an informal theory that complements Bishop's theory of sets, to the theory of Bishop spaces, a function-theoretic approach to constructive topology. Within BST we develop the notions of a direct family of sets, of a direct spectrum of Bis...

description | We apply fundamental notions of Bishop set theory (BST), an informal theory
that complements Bishop's theory of sets, to the theory of Bishop spaces, a
function-theoretic approach to constructive topology. Within BST we develop the
notions of a direct family of sets, of a direct spectrum of Bishop spaces, of
the direct limit of a direct spectrum of Bishop spaces, and of the inverse
limit of a contravariant direct spectrum of Bishop spaces. Within the extension
of Bishop's informal system of constructive mathematics BISH with inductive
definitions with rules of countably many premises, we prove the fundamental
theorems on the direct and inverse limits of spectra of Bishop spaces and the
duality principle between them. |
