NONSTANDARD MODELS IN RECURSION THEORY AND REVERSE MATHEMATICS

The Bulletin of Symbolic Logic, 2014
AbstractWe give a survey of the study of nonstandard models in recursion theory and reverse mathematics. We discuss the key notions and techniques in effective computability in nonstandard models, and their applications to problems concerning combinatorial principles in subsystems of second order arithmetic.

Analysis of a mathematical model for cancer treatment by the nonstandard finite difference methods

Journal of Difference Equations and Applications, 2017
AbstractWe construct two nonstandard finite difference schemes and use them to study a mathematical model of cancer therapy. Several recent studies show various aspects of the immune response against the cancer. Our discrete models emphasize the role of antibodies in any form of therapy by taking into account the development of anticancer therapies ...

A nonstandard finite difference method for solving a mathematical model of HIV-TB co-infection

Journal of Difference Equations and Applications, 2017
We design and analyze an unconditionally convergent nonstandard finite-difference method to study transmission dynamics of a mathematical model of HIV-TB co-infection. The dynamics of this model are studied using the qualitative theory of dynamical systems. These qualitative features of the continuous model are preserved by the numerical method that we
