Set theory is the branch of mathematical logic that studies sets, which can be informally described as collections of objects. Although objects of any kind can be collected into a set, set theory — as a branch of mathematics — is mostly concerned with those that are relevant to mathematics as a whole.

Fuzzylogik (englisch fuzzy ‚verwischt‘, ‚verschwommen‘, ‚unbestimmt‘; fuzzy logic, fuzzy theory ‚unscharfe Logik‘ bzw. ‚unscharfe Theorie‘) oder Unschärfelogik ist eine Theorie, welche in der Mustererkennung zur „präzisen Erfassung des Unpräzisen“ entwickelt wurde, sodann der Modellierung von Unschärfe von umgangssprachlichen ...
Set theory is a branch of mathematics that studies sets, which are essentially collections of objects. For example \ {1,2,3\} {1,2,3} is a set, and so is \ {\heartsuit, \spadesuit\} {♡,♠}.
30. Nov. 2014 · Set theory is the study of the properties of sets (cf. Set) by themselves, disregarding the properties of their elements. It is especially concerned with the study of sets with infinite elements. The idea of a set is one of the primitive mathematical ideas and can only be explained by means of examples or analogies.
