Remarks on a Constructive Sheaf Model of Nonstandard Analysis
نویسنده
چکیده
The sheaves over the category of lters, with a joint cover topology, serve as a universe of sets where nonstandard analysis can be developed along constructive principles. In this paper we show that all functions between internal sets in this model are internal. We also illustrate how this model can be used by giving a constructive nonstandard proof of the Implicit Function Theorem.

Nonstandard Functional Interpretations and Categorical Models
Recently, the second author, Briseid and Safarik introduced nonstandard Dialectica, a functional interpretation that is capable of eliminating instances of familiar principles of nonstandard arithmetic including overspill, underspill, and generalisations to higher types from proofs. We show that, under few metatheoretical assumptions, the properties of this interpretation are mirrored by first ...
متن کاملAlgorithm and proof as Ω-invariance and transfer: A new model of computation in nonstandard analysis
We propose a new model of computation based on Nonstandard Analysis. Intuitively, the role of ‘algorithm’ is played by a new notion of finite procedure, called Ω-invariance and inspired by physics, from Nonstandard Analysis. Moreover, the role of ‘proof’ is taken up by the Transfer Principle from Nonstandard Analysis. We obtain a number of results in Constructive Reverse Mathematics to illustra...
متن کاملA nonstandard proof of a lemma from constructive measure theory
The conceptual gulf between constructive analysis (in the sense of Bishop [1]) and nonstandard analysis (in the sense of Robinson [7]) is vast, despite the historical genesis of both methodologies from foundational considerations. Those who use nonstandard arguments often say of their proofs that they are “constructive modulo an ultrafilter”; implicit in this statement is the suggestion that su...
متن کاملConstructive Nonstandard Representations of Generalized Functions
Using techniques of nonstandard analysis Abraham Robinson showed that it is possible to represent each Schwartz distribution T as an integral T () = R f, where f is some nonstandard smooth function. We show that the theory based on this representation can be developed within a constructive setting.
متن کاملA numerical method for discrete fractional--order chemostat model derived from nonstandard numerical scheme
In this paper, the fractional--order form of three dimensional chemostat model with variable yields is introduced. The stability analysis of this fractional system is discussed in detail. In order to study the dynamic behaviours of the mentioned fractional system, the well known nonstandard (NSFD) scheme is implemented. The proposed NSFD scheme is compared with the forward Euler and ...
