The axioms of IST is the axioms of ZFC together with three additional axioms which are called the transfer axiom, the idealization axiom and the standardization axiom .They are as follow: Transfer Axiom [6]: for each standard formula F(x,t1,t2,…,tn) with only free variables x,,t1,t2,…., t n , the fo ...

... for every x ∈ R. Definition 2.15. If a set A ⊂ R is not bounded from above, then sup A = ∞, and if A is not bounded from below, then inf A = −∞. For example, sup N = ∞ and inf R = −∞. We also define sup ∅ = −∞ and inf ∅ = ∞, since — by a strict interpretation of logic — every real number is both an ...

... A set with no upper bound is said to be unbounded above. Definition 2 (Lower bound). Let S be a set of real numbers. If there is a real number b such that x ≥ b, for every x ∈ S, then b is call a lower bound for S and we say that S is bounded below by b. We say a lower bound because every number les ...
