  106. Everybody’s Mathematics – Maximal Emulation Stability, 15
pages, June 7, 2018.

In [1], we have simplified the solitaire games considerably by
removing all of the "infinities" thee. We have also added FMES =
finite MES

Abstract. MES is Maximal Emulation Stability, the lead statement in
the new Emulation Theory. MES asserts that every finite subset of
Q[0,k]^k has a stable maximal emulator. MES is sufficiently natural,
transparent, concrete, elementary, interesting, memorable, teachable,
rich in varied intricate examples, and rich in weaker and stronger
forms, that it merits being classified in the category of Everybody's
Mathematics. MES is readily seen, via Gödel's Completeness Theorem, to
be implicitly Pi01. MES is independent of the usual ZFC axioms for
mathematics, being equivalent to Con(SRP), where SRP is ZFC together
with certain large cardinal hypotheses well investigated and accepted
by set theorists. We also discuss GMES = General Maximal Emulation
Stability, a natural transparent generalization, and Finite Maximal
Emulation Stability = FMES, both explicitly Pi01 and equivalent to
Con(SRP). We conclude with other explicitly Pi01 forms in the shape of
playable solitaire games. We argue that winning these games
constitutes confirmation of the consistency of mathematics.
