Transfer of canonical hyperreal evaluations to improved number systems
Prove that in any improved or alternative theory of summation and integration built on a different infinite number system (such as the surreal numbers), the canonical evaluations produced by hyperreal summation and integration transfer; specifically, establish that the improper integral of 1/x from 1 to infinity equals log(+), where + denotes the simple, canonical infinite element of that alternative number system.
References
I conjecture that the canonical answers given by the hyperreal theory will transfer to any improved theories. For instance, that the integral from 1 to 00 of 1/x will equal log(+) where + is a simple and canonical infinite number in that theory.
