Introduction to HyperReals
... Since b is finite there are real numbers s and t with s < b < t. Let A = { x | x is real and x < b }. A is non-empty since it contains s and is bounded above by t. Thus there is a real number r which is the least upper bound of A. We claim r b. Suppose not. Thus r b and Hence r-b is positive or ...

As irrational powers are hard to understand, it is not immediately apparent that this problem admits a short, elementary solution. One can overcome the difficulty by using the value of xx to study x. In fact the equation xx ...

Formal Theories of Truth INTRODUCTION

Note on a conjecture of PDTA Elliott
... As we mentioned in the first section of the present paper, for Rosen's question only a restricted form of Elliott's conjecture has importance. In this paragraph we shall prove a partial result on this restricted form of Elliott's conjecture. Namely we shall prove the following Theorem 2. Let n > \ b ...
