Mirror Symmetry as a Gauge Symmetry [PDF]

open access: yesPhysics Letters B, 1994
It is shown that in string theory mirror duality is a gauge symmetry (a Weyl transformation) in the moduli space of $N=2$ backgrounds on group manifolds, and we conjecture on the possible generalization to other backgrounds, such as Calabi-Yau manifolds ...

Exact Solutions and Conserved Vectors of the Two-Dimensional Generalized Shallow Water Wave Equation

open access: yesMathematics, 2021
In this article, we investigate a two-dimensional generalized shallow water wave equation. Lie symmetries of the equation are computed first and then used to perform symmetry reductions.

Symmetry-break in Voronoi tessellations [PDF]

open access: yes, 2009
We analyse in a common framework the properties of the Voronoi tessellations resulting from regular 2D and 3D crystals and those of tessellations generated by Poisson distributions of points, thus joining on symmetry breaking processes and the approach ...

PT-symmetry broken by point-group symmetry [PDF]

open access: yes, 2013
We discuss a PT-symmetric Hamiltonian with complex eigenvalues. It is based on the dimensionless Schr\"{o}dinger equation for a particle in a square box with the PT-symmetric potential $V(x,y)=iaxy$.

A symmetry for vanishing cosmological constant [PDF]

open access: yes, 2006
Two different realizations of a symmetry principle that impose a zero cosmological constant in an extra-dimensional set-up are studied. The symmetry is identified by multiplication of the metric by minus one. In the first realization of the symmetry this
