Gluon confinement and quantum censorship
The dynamical Maxwell-cut, a degeneracy is shown to be a precursor of
condensate in the phi4 and the sine-Gordon models. The difference of the way
the Maxwell-cut is obtained is pointed out and quantum censorship, the
generation of semiclassically looking phenomenon by loop-corrections is
conjectured in the sine-Gordon model. It is argued that quantum censorship and
gluon confinement exclude each other.Comment: Talk prepared for the conference "Gribov-80", May 26-28, 2010, ICTP

Spinodal Instability and Confinement
It is pointed out that inhomogeneous condensates or spinodal instabilities
suppress the propagation of elementary excitations due to the absorptive zero
mode dynamics. This mechanism is shown to be present in the scalar phi4 model
and in Quantum Gravity. It is conjectured that the plane waves states of color
charges have vanishing scattering amplitude owing to the color condensate in
the vacuum.Comment: Talk presented at the Workshop GRIBOV-75, Budapest, May 2005, 12

Patterns of primes
In the present work the existence of some patterns of primes is shown which
generalize the celebrated result of Green and Tao according to which there are
arbitrarily long arithmetic progressions in the sequence of prime
Environment Induced Time Arrow and the Closed Time Path method
It is shown in the framework of a harmonic system that the thermodynamical
time arrow is induced by the environmental initial conditions in a manner
similar to spontaneous symmetry breaking. The Closed Time Path formalism is
introduced in classical mechanics to handle Green functions for initial
condition problems by the action principle, in a systematic manner. The
application of this scheme for quantum systems shows the common dynamical
origin of the thermodynamical and the quantum time arrows. It is furthermore
conjectured that the quantum-classical transition is strongly coupled.Comment: 10 pages, 1 figures, talk presented at DICE2012, Castiglioncello,

An exact solution of the Currie-Hill equations in 1 + 1 dimensional Minkowski space
We present an exact two-particle solution of the Currie-Hill equations of
Predictive Relativistic Mechanics in dimensional Minkowski space. The
instantaneous accelerations are given in terms of elementary functions
depending on the relative particle position and velocities. The general
solution of the equations of motion is given and by studying the global phase
space of this system it is shown that this is a subspace of the full kinematic
phase space.Comment: 13 pages, LaTeX. arXiv admin note: text overlap with arXiv:1402.699
