One example is Presburger arithmetic, in which the universe is the natural numbers and there is a single function, plus, whose properties are axiomatized. There ar ...

Infinity 1. Introduction

The points at infinity in projective geometry are very different from the infinite and infinitesimal quantities that occur in nonstandard analysis, or the transfinite numbers in set theory, or the infinity involved in a limiting process limn→∞ ...
