Definition of an Equivalence Relation A binary relation on a non-empty set A is said to be an equivalence relation if and only if the relation is : //be aware of the true meaning of a binary relation R on a set A. refers to :Properties of Relations (Set Theory 2). // reflective ...
A binary relation R defined on a set A may have the following properties. //The properties of relation is defined on the relational SET A itself-i.e. members which form the relation R . DONT mix it…
including asymptotic analysis, dynamical systems, and model theory of the real numbers. The first-order theory of (logarithmic-exponential) transseries and maximal Hardy fields is completely axiomatized by the theory of closed H-fields, which is model complete, as Aschenbrenner, Van den Dries, an...

We present axiomatizations of the two main set theories: the Theory of Types and Zermelo-Fraenkel Set Theory. We present some basic facts about the arithmetic of infinite cardinal and ordinal numbers. We introduce the concept of large cardinals, which ar

Let's clarify the concept we just used for the fundamental inclusion ordering of set theory: Minimal and maximal points in a partially ordered set (poset) F : Considering a set F endowed with a partial ordering relation: An element is minimal when no other element of F is below it. An...
