Extended symmetry groups of multidimensional subshifts with hierarchical structure
(American Institute of Mathematical Sciences, 2020)
The centralizer (automorphism group) and normalizer (extended symmetry group) of the shift action
inside the group of self-homeomorphisms are studied, in the context of certain Z(d) subshifts with a
hierarchical supertile ...
Radial symmetry of ground states for a regional fractional nonlinear schrödinger equation
(2014)
The aim of this paper is to study radial symmetry properties for ground state solutions of elliptic equations involving a regional fractional Laplacian, namely
(-[delta])[alfa][ro][ípsilon]+u = f(u)in Rn, for [alfa] ...
DYNAMICAL SYMMETRY BREAKING IN A MINIMAL 3-3-1 MODEL
(World Scientific Publ Co Pte Ltd, 2012-10-20)
The gauge symmetry breaking in some versions of 3-3-1 models can be implemented dynamically because at the scale of a few TeVs the U(1)(X) coupling constant becomes strong. In this work, we consider the dynamical symmetry ...

Loop algebra and visaoro symmetries of integrable hierarchies of KP type
(2001-01-01)
We propose a systematic treatment of symmetries of KP integrable systems, including constrained (reduced) KP models cKP R, M (generalized AKNS hierarchies), and their multi component (matrix) generalizations. Any cKP R, M ...
On the Geometry of Symmetry Breaking Inequalities
(SPRINGER INTERNATIONAL PUBLISHING AG, 2021)
Breaking symmetries is a popular way of speeding up the branch-and-bound method for symmetric integer programs. We study polyhedra that break all symmetries, namely, fundamental domains. Our long-term goal is to understand ...
A Cooperation between Fluctuations and Spatial Coupling for Two Symmetry-Breakings in a Gradient System
(American Physical Society, 2015-12)
A zero-dimensional system that is affected by the field´s dependent fluctuations evolves toward field´s values in which the fluctuations´ effect is minimized. For a high enough noise intensity, it causes an exchange of ...
Symmetry breaking for an elliptic equation involving the fractional Laplacian.
(Khayyam Publishing, Inc., 2018-08)
We study the symmetry breaking phenomenon for an elliptic equation involving the fractional Laplacian in a large ball. Our main tool is an extension of the Strauss radial lemma involving the fractional Laplacian, which ...
