There has been significant improvements of various kinds, both
expositional and mathematical. For the general formulations, we now
use order theoretic partial f:J into J that are strictly increasing
and continuous, for the embeddings of maximal cliques in order
invariant graphs on J^k. Here J is a rational interval.
We have greatly improved the explicitly finite and explicitly Pi01
statements, and also the discussion of computer investigations.
FROM THE MANUSCRIPT:
Abstract. We investigate "every order invariant graph on every
Cartesian power of J has an f embedded maximal clique", where J be a
rational interval and f:J into J is partial. For f with finite domain, we
give an elegant necessary and sufficient condition. For general f, it
is necessary that f be strictly increasing, and the investigation of
sufficient conditions leads to statements with unexpected logical
properties. The statements have the ZFC refutation property - it is
provable from the usual ZFC axioms for mathematics, that if the
statement is false then it is refutable in ZFC. The statements are
demonstrably equivalent to the generally believed Con(SRP), which
asserts the consistency of ZFC augmented by a well studied large
cardinal hypothesis. Thus the statements cannot be proved in ZFC
(assuming ZFC is consistent). This phenomena emerges even for
numerical shift functions f:Q>=0 into Q>=0. We investigate associated
infinite sequential constructions and show that "such infinite
constructions have output" is also demonstrably equivalent to
Con(SRP). We present five finite approximations to these
constructions, within the realm of finite mathematics, with the ZFC
refutation property. These statements are in explicitly Pi02, Pi01, Pi04,
Pi02, Pi02 form. The last four are provably equivalent to Con(SRP).
Iterated exponential bounds on the existential quantifiers put the
last three in explicitly Pi01 form. We conclude with a discussion of
associated computer investigations, leading to the prospect of the
confirmation of Con(SRP) by actual practical computer implementations.
