Subject: New mailing list: PetriPhysics

Estimados,
I've created the list PetriPhysics (as response to the responses of at
the moment eight persons). 
The objectives are described below. Abstracts -resuming susbstantial
contributions- will be posted to the general PetriNets mail list.
To subscribe send (as usual) a mailto: majordomo@fenix.sasa.com.ni
<mailto:majordomo@fenix.sasa.com.ni>  with the only line subscribe
petriphysics 
There will be -to avoid spamming and spoofing- a return-email where you
are asked to confirm (or not) your subscription. 
The list is not moderated.

PetriPhysics
This list is dedicated to a very special nontheless fundamental topic:
The (possible) relation between basic combinatorial structures as
introduced by Petri, namely structures defined by 2 (3) Relations
 co (concurrency) 
 li (on a line or casual dependend) 
 [and al, alternative because of choice]
and basic structures in Physics 
 Time, Space and Geometry (Relativity, both special and general)
 Physical Invariants (Classical: Mecanics, Thermo- and Electrodynamics)
 Quantum Invariants
where it is known (all the bunch of higher-level Petri-Net
interpretations) that the former are closely related with
Information-processing (general) and for the latter there are
Information relevant interpretations. 

Petri's basic ideas introduce a combinatorial model both of Time-Space
and physical processes closely related with information. 
The list was created to explore these basic ideas, compare them with
other combinatorial or continuos models (like cellular automata)for
Time-Space and Processes including the different interpretations and
models for Quantum-Physics or the more recent theories of unification
like string-theory.

Though concieved as a Chat-Board to interchange ideas, questions and may
be some answers, contributions should be based on some type of formal
argument where references can be made to Mathematics (in almost all its
branches),
Physics and Informatics.

It's moreover assumed that contributors and readers have at least some
basic knowledge of Petri's work (or don't complain if others assume this
knowlegde).
[Not for arrogant, just to shortcut communication like in other
disciplines, where basic terminology is taken for granted]

The list-host

[This is just a private activity not related with -at least directly- to
what I'm doing for living]
