Finite Canonical Commutation Relations
You can never solve a problem on the level on which it was created.
-- Albert Einstein (1879-1955)
"Silence will save me from being wrong (and foolish), but it will also
deprive me of the possibility of being right.

A working paper on FCCR nxn matricies as local kinematical replacement for CCR,
and construction of REPS of CCR by pxp matricies over Galois fields.
Some remaining text of the chapters is still being
translated to hypertext.
An abstract and a brief summary of the essentials are available.
The central object of interest here is a chain of algebras
given in terms of nxn complex matricies that connect the
quantum mechanical Canonical Commutation Relations (CCR) for
n unbounded with the Canonical Anticommutation Relations (CAR) for n=2,
which seem to provide a local, finite, discrete quantum theory.
Finite dimensional representations of CCR by matricies over Galois
fields are constructed in appendix J.
The detail of mathematics, physics and philosophy presented here is far
more than what would be usual in an any professional journal.
I believe it to be sufficient that any mathematician/physicist should be
able to reproduce and confirm (or correct!) every detail in the
