Realizability of matroid quotients [PDF]

open access: yes
We characterize the realizability of a quotient of matroids, over an infinite field $K$, in terms of the realizability over $K$ of a single matroid associated to it, called the Higgs major. This result extends to realizability of flag matroids.

Realizability Models for Sequential Computation

open access: yes, 1998
We give an overview of some recently discovered realizability models that embody notions of sequential computation, due mainly to Abramsky, Nickau, Ong, Streicher, van Oosten and the author. Some of these models give rise to fully abstract models of PCF;

Sheaf Toposes for Realizability

open access: yes, 2001
We compare realizability models over partial combinatory algebras by embedding them into sheaf toposes. We then use the machinery of Grothendieck toposes and geometric morphisms to study the relationship between realizability models over different ...

Realizability categories

open access: yes, 2013
The thesis is a comprehensive analysis of realizability toposes, which is divided into three central chapters. The first chapter considers a class of realizability models which are a generalization of realizability triposes, and derives a collection of ...

An Extensional Modified Realizability Topos

open access: yes
In this thesis, we construct and investigate a topos for Kreisel’s modified realizability. The topos, like Kreisel’s modified realizability, is characterized by the axiom of choice in all finite types and the principle of independence of premise.

Realization Universality

open access: yes
This paper explores the concept of realization universality, focusing on identifying minimal universal realization families for a large class of functions. The core objective is to determine if, for a vast set of functions [f ∈ F], a small family [U] exists such that each function [P_f] can be represented within [U]. The theoretical framework presented
