F-theory on quotients of elliptic Calabi-Yau threefolds
Journal of High Energy Physics, 2019 In this work we consider quotients of elliptically fibered Calabi-Yau threefolds by freely acting discrete groups and the associated physics of F-theory compactifications on such backgrounds.

On spinless null propagation in five dimensional space-times with approximate space-like Killing symmetry [PDF]
, 2016 Five-dimensional (5D) space-time symmetry greatly facilitates how a 4D observer perceives the propagation of a single spinless particle in a 5D space-time.

u-Deformed WZW Model and Its Gauging [PDF]
, 2006 We review the description of a particular deformation of the WZW model. The resulting theory exhibits a Poisson-Lie symmetry with a non-Abelian cosymmetry group and can be vectorially gauged.Comment: This is a contribution to the Proc.

Electroweak Interaction Model with an Undegenerate Double Symmetry [PDF]
, 2005 The initial $P$-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.

Gauge symmetry enhancement in Hamiltonian formalism
, 2003 We study the Hamiltonian structure of the gauge symmetry enhancement in the enlarged CP(N) model coupled with U(2) Chern-Simons term, which contains a free parameter governing explicit symmetry breaking and symmetry enhancement.

Di-μ-sulfato-bis{[bis(3,5-dimethylpyrazol-1-yl)methane]copper(II)}
Acta Crystallographica Section E, 2008 The molecule of the title compound, [Cu2(SO4)2(C11H16N4)2], sits on a center of symmetry. The CuII atom has a distorted trigonal–bipyramidal coordination geometry comprising three O atoms of the two symmetry-related SO42− anions and two N ...

Group Analysis of Born-Infeld Equation [PDF]
arXiv, 2010 Lie symmetry group method is applied to study the Born-Infeld equation. The symmetry group and its optimal system are given, and group invariant solutions associated to the symmetries are obtained. Finally the structure of the Lie algebra symmetries is determined.
