Nonstandard second-order arithmetic and Riemann's mapping theorem [PDF]
In this paper, we introduce systems of nonstandard second-order arithmetic which are conservative extensions of systems of second-order arithmetic. Within these systems, we do reverse mathematics for nonstandard analysis, and we can import techniques of ...

Nonstandard Version of Intermediate Value Property
In this paper, some new properties and results about Intermediate Value Property (IVP) via nonstandard concepts are given, and modifying some existing results to show the advantage role of nonstandard analysis tools for obtaining differed nonstandard ...

Some Nonstrandard Result of Continuous, Monotonic Functions [PDF]
The aim of this paper is to use some concepts of nonstandard analysis given by Robinson, [8], and axiomatized by Nelson,E. [6] to present a new result of continuous and monotonic function when they are defined on nonstandard sets.

Examples and counterexamples regarding hyperfinite representations of real distributions
We provide some examples and counterexamples regarding hyperfinite representations of real distributions. We examine some hyperfinite representatives of the null distribution and of the Dirac distribution, we discuss hyperfinite representations of an ...

An operator equation and relativistic alterations in the time for radioactive decay
In this paper, using concepts from the nonstandard physical world, the linear effect line element is derived. Previously, this line element was employed to obtain, with the exception of radioactive decay, all of the experimentally verified special theory

ON SOME NONSTANDARD DEVELOPMENTS OF INTERMEDIATE VALUE PROPERTY [PDF]
In this paper, by using the power of nonstandard analysis tools, we review some of the standard facts on the intermediate value property (IVP) and investigates some new nonstandard developments by extending the classical definition.

On differential operators an differential equations on torus
In this paper, we consider periodic boundary value problems for a differential equation whose coefficients are trigonometric polynomials. The spaces of generalized functions are constructed, in which the problems considered have solutions, in particular,
