A Constructive Morse Theory of Sets
1987In this paper I shall outline a foundational system for constructive mathematics analogous to that given in [11] for classical mathematics. By ‘constructive mathematics’ I shall mean mathematics as understood by Errett Bishop and his followers [2, 3], the mathematics of which the primary concern … is number, and this means the positive integers ...

Set theory with free construction principles
1983In set theory with the axiom of foundation, the \(\in\)-relations on transitive classes are up to isomorphism just the extensional well-founded relations. In the absence of the axiom of foundation one may require various axioms of universality (e.g. that every binary relation (which is extensional) has an homomorphism (an isomorphism, resp.) onto the \(

Equalisers of Frames in Constructive Set Theory
2011In a recent note (Palmgren, 2005) Erik Palmgren has shown that, in a sufficiently strong version of Martin-Lof’s type theory (Martin-Lof, 1984) the category of set-presented formal topologies has coequalisers. We refer the reader to (Palmgren, 2005) for the background motivation for this result.

A constructive set theory for program development
1988We present a constructive theory of types and kinds (called TK5) designed with program development as the major desideratum. We motivate its definition with respect to existing research in the area of program logics (in particular Martin-Lof's theory of types) and establish suitable infrastructure for program extraction from proofs of specifications.

Constructive Hovels for Set Theory with Extensionalitv
1982Publisher Summary This chapter discusses various constructive models for set theory with extensionality. There are two well-known methods that can be used to interpret J.Myhill-style extensional constructive set theories within subsystems of analysis and S.Feferman-style constructive systems of functions and classes.

The Existence Property in Constructive Set Theory
1985This chapter is primarily of technical interest, in the sense that nothing in the rest of the book depends upon it, and in the sense that the proofs are rather complicated. Nevertheless, the existence property has attracted considerable attention, since many people feel a constructive theory “ought to” have the existence property.
