The idea about primes as 'minimal systems' resonates with my own
thinking. I have also played with the idea about prime numbers as minimal
systems, minimal system regarded now as elementary particle. Prime number
decomposition for integer n= prod_k p_k^(n^k) is like many particle state
containing n_k elementary particles (bosons) of type p_k.

In the construction of infinite primes this idea comes very concrete
and a direct connection with the state construction of supersymmetric of
QFT:s emerges. For instance, the following numbers are rather general
infinite primes (or good candidates for them):

P = m*X/S + n* S

X= prod_kp_k is product of *all* finite primes. It is like *Dirac sea*
with all fermion states labelled by primes p_k filled.

S= is product of finite primes of form S= prod_{i in S}p_i. Only *first
powers of p_i* appear: S corresponds to n-fermion state and first powers
mean exclusion principle! What has been done is to kick some fermions
from sea so that holes are formed (formation of X/S and S).

m = prod_k p_k^(n^k) is integer *not divided* by primes dividing S.

n= prod_ip_i^(n^i) is integer not divided by primes dividing X/S.
m*X/S and n*S have no common (prime) divisors and this in fact implies
primeness since P mod finite prime is always nonvanishing.

m*n can be interpreted as many boson sates: n_r bosons of type p_r.

Thus P corresponds to many particle state of super symmetric theory with
finite primes labeling various fermionic and bosonic modes.

P has two parts. Since n*S can be finite it has interpretation
as a subsystem (local system!) and m*X/S is interpreted as its
complement so that subsystem complement separation crucial for strong NMP
and TGD inspired theory of consciousness appears naturally.

[I end up with a concrete translation of this analogy to real
decomposition at the level of spacetime surface: the hypothesis is
that the infinite prime characterizing the asymptotic p-adic
effective topology of spacetime surface codes the information about
various p-adic regions contained by the spacetime surface of infinite
size.]

Primeness follows from the fact that any finite p divides either m*X/S
or n*S but never both of them. This, if there are no
infinite primes with representation which is something which I have not
being able to imagine. The beautiful analogy with supersymmetric QFT:s
makes me believe that primes are indeed in question.
