Simplicial quantum dynamics
Present-day quantum field theory can be regularized by a decomposition into
quantum simplices. This replaces the infinite-dimensional Hilbert space by a
high-dimensional spinor space and singular canonical Lie groups by regular spin
groups. It radically changes the uncertainty principle for small distances.
Gaugeons, including the gravitational, are represented as bound fermion-pairs,
and space-time curvature as a singular organized limit of quantum
non-commutativity.
Keywords: Quantum logic, quantum set theory, quantum gravity, quantum
topology, simplicial quantization.Comment: 25 pages. 1 table. Conference of the International Association for

A framework for proving the self-organization of dynamic systems
This paper aims at providing a rigorous definition of self- organization, one
of the most desired properties for dynamic systems (e.g., peer-to-peer systems,
sensor networks, cooperative robotics, or ad-hoc networks). We characterize
different classes of self-organization through liveness and safety properties
that both capture information re- garding the system entropy. We illustrate
these classes through study cases. The first ones are two representative P2P
overlays (CAN and Pas- try) and the others are specific implementations of
\Omega (the leader oracle) and one-shot query abstractions for dynamic
settings. Our study aims at understanding the limits and respective power of
existing self-organized protocols and lays the basis of designing robust
algorithm for dynamic systems
Least-action perihelion precession
The precession of Mercury's perihelion is reinspected by the principle of
least action. The anomalous advancement of the apside line that is customarily
accounted by the theory of general relativity, is ascribed to the gravitational
effect due to the entire Universe. When the least action is written in the
Sun's frame of reference, the residual rotation is seen to stem from inertia
due to all bodies in the Universe. Since mass corresponds to a bound form of
energy, gravity, as any other force, can be described as an energy density
difference between a system of bodies and its surrounding energy densities that
are dispersed throughout the Universe. According to the principle of least
action the Universe is expanding by combustion of mass to radiation in the
quest of equilibrating the bound forms of energy with "zero-density
surroundings" in least time. Keywords: cosmological principle; energy density;
energy dispersal; evolution; gravity; the principle of least actionComment: 7 pages, 3 figure
