Nonstandard Analysis

Nonstandard analysis is a branch of mathematical Logic which weakens the axioms of usual Analysis to includeonly the first-order ones. It also introduces Hyperreal Numbers to allow for the existence of``genuine Infinitesimals,'' numbers which are less than 1/2, 1/3, 1/4, 1/5, ..., but greaterthan 0. Abraham Robinson developed nonstandard analysis in the 1960s. The theory has since been investigated for its ownsake and has been applied in areas such as Banach Spaces, differential equations, probabilitytheory, microeconomic theory, and mathematical physics (Apps).
