Neutrality and Many-Valued Logics
In this book, we consider various many-valued logics: standard, linear,
hyperbolic, parabolic, non-Archimedean, p-adic, interval, neutrosophic, etc. We
survey also results which show the tree different proof-theoretic frameworks
for many-valued logics, e.g. frameworks of the following deductive calculi:
Hilbert's style, sequent, and hypersequent. We present a general way that
allows to construct systematically analytic calculi for a large family of
non-Archimedean many-valued logics: hyperrational-valued, hyperreal-valued, and
p-adic valued logics characterized by a special format of semantics with an
appropriate rejection of Archimedes' axiom. These logics are built as different
extensions of standard many-valued logics (namely, Lukasiewicz's, Goedel's,
Product, and Post's logics). The informal sense of Archimedes' axiom is that
anything can be measured by a ruler. Also logical multiple-validity without
Archimedes' axiom consists in that the set of truth values is infinite and it
is not well-founded and well-ordered. On the base of non-Archimedean valued
logics, we construct non-Archimedean valued interval neutrosophic logic INL by
which we can describe neutrality phenomena.Comment: 119 page
Periodic -adic Gibbs measures of -states Potts model on Cayley tree: The chaos implies the vastness of -adic Gibbs measures
We study the set of -adic Gibbs measures of the -states Potts model on
the Cayley tree of order three. We prove the vastness of the periodic -adic
Gibbs measures for such model by showing the chaotic behavior of the
correspondence Potts--Bethe mapping over for $p\equiv 1 \
(\rm{mod} \ 3)0 < |\theta-1|\_p < |q|\_p^2 < 10 < |q|\_p^2 \leq |\theta-1|\_p < |q|\_p < 1rr \geq 4rpp=2,30 < |\theta-1|\_p <
|q|\_p < 1,p=2,\
p=3p\equiv 2 \ (\rm{mod} \ 3)p0 < |q|\_p \leq |\theta-1|\_p < 1p$
Renormalization method in -adic -model on the Cayley tree
In this present paper, it is proposed the renormalization techniques in the
investigation of phase transition phenomena in -adic statistical mechanics.
We mainly study -adic \l-model on the Cayley tree of order two. We
consider generalized -adic quasi Gibbs measures depending on parameter
\r\in\bq_p, for the \l-model. Such measures are constructed by means of
certain recurrence equations. These equations define a dynamical system. We
study two regimes with respect to parameters. In the first regime we establish
that the dynamical system has one attractive and two repelling fixed points,
which predicts the existence of a phase transition. In the second regime the
system has two attractive and one neutral fixed points, which predicts the
existence of a quasi phase transition. A main point of this paper is to verify
(i.e. rigorously prove) and confirm that the indicated predictions (via
dynamical systems point of view) are indeed true.
To establish the main result, we employ the methods of -adic analysis, and
therefore, our results are not valid in the real setting.Comment: 18 page
