... The above-mentioned method of using model theory cannot superstandardize all of mathematics at once. Around 1977, E. Nelson and K. Hrbacek added new predicates or constants (the entire set of standard sets and the entire set of inner sets) to the usual set theory (Zermelo-Fraenkel theory) and added some axioms (including the principle of co-occurrence) to create superstandard set theory. This theory includes all of existing mathematics and is a convenient theory that can also develop superstandard analysis. ...
