We restart the part of
https://cs.nyu.edu/pipermail/fom/2017-December/020746.html concerning
Concrete Mathematical Incompleteness. The paper
http://u.osu.edu/friedman.8/foundational-adventures/downloadable-manuscripts/
#92
is to appear, and will not be modified to take into account major
subsequent developments.
We now have several breakthroughs beyond

Here is the front end of the paper

CONCRETE MATHEMATICAL INCOMPLETENESS STATUS 2/8/18

The book is expected to have three major parts:
CONCRETE MATHEMAITCAL INCOMPLETENESS
PART 1. BOOLEAN RELATION THEORY.
PART 2. EMULATION THEORY.
PART 3. INDUCTIVE EQUATION THEORY.
THIS TABLE OF CONtENTS
1. Emulation Theory/infinite/SRP.
2. Inductive Equation Theory/infinite/SRP.
3. Inductive Equation Theory/infinite/HUGE.
4. Inductive Equation Theory/finite/SRP.
5. Inductive Equation Theory/finite/HUGE.
I have recently been determined to move to functions rather than stick
with sets. However, I have now realized how I can do more with sets
than I had previously thought, and certain things are more naturally
transparent with sets.
So I am now moving back to sets throughout.

EXTENDED REMARKS
In this posting, I want to make some extended remarks.
I view these as the advanced stages after about 50 years of progress: :
...
...
...
STAGE n. Perfectly Natural, Simple, Transparent, Easily Explained,
etcetera. Always implicitly Pi01, and sometimes explicitly Pi01, and
always independent of ZFC.
STAGE n+1. Of clear interest to a significant portion of the
mathematical community, as pieces of mathematics, independent of the
significance for the foundations of mathematics. Always implicitly
Pi01, and sometimes explicitly Pi01, and always independent of ZFC.
Measured how? By seminar talks
and colloquium lectures in core mathematical venues across the globe.
STAGE n+2. A clear Thematic Principle, with immediately striking
resonance, that cuts across virtually all areas of mathematics,
opening up a myriad of related investigations, with unexpected
outcomes relating to existing research.
STAGE n+3. New mathematical tools, based on a clear thematic principle
from stage n+2, that provides necessary uses of large cardinals to
obtain consensus significant theorems across mathematics.
Over the years, I had no confidence that I would ever reach stage n.
Yet we are here, in the middle of stage n, moving steadily along.
Things are getting yet simpler, yet more transparent, and yes, yet
more Perfectly Natural. This is not yet fully played out.
But as a consequence of this, we are seriously approaching Stage n+1,
at least knocking on the door. There is also definitely a small
GLIMPSE at stage n+2. Stage n+3 is still far removed.
NOW THERE is an important distinction here. For mathematicians with
serious Foundational Interests and Sensibilities, they are going to be
already interested in STAGE n statements FOR THEIR
FOUNDATIONAL INTEREST. I.e., that Stage n statements ACTUALLY EXIST,
contrary to CW. THAT is to be distinguished from being
interested purely mathematically.That is stage n+1.
With regard to Stage n+2, we are definitely moving to themes like:
REGULARITY IN MAXIMAL OBJECTS
and similar phrases.
