Enlargement of symmetry groups in physics: a practitioner's guide
Lehel Csillag, Julio Marny Hoff da Silva, Tudor Patuleanu
Wigner's classification has led to the insight that projective unitary representations play a prominent role in quantum mechanics. The physics literature often states that the theo…
Cosmological Landsberg Finsler spacetimes
Annamária Friedl-Szász, Elena Popovici-Popescu, Nicoleta Voicu +2
We locally classify all possible cosmological homogeneous and isotropic Landsberg-type Finsler structures, in 4-dimensions. Among them, we identify viable non-stationary Finsler sp…
Metric-affine cosmological models and the inverse problem of the calculus of variations. Part 1: variational bootstrapping -- the method
Ludovic Ducobu, Nicoleta Voicu
The method of variational completion allows one to transform an (in principle, arbitrary) system of partial differential equations -- based on an intuitive ``educated guess'' -- in…
Canonical variational completion of differential equations
Nicoleta Voicu, Demeter Krupka
Given a non-variational system of differential equations, the simplest way of turning it into a variational one is by adding a correction term. In the paper, we propose a way of ob…
Jet theoretical Yang-Mills energy in the geometric dynamics of 2D-monolayer
M. Neagu, N. G. Krylova, H. V. Grushevskaya
Langmuir-Blodgett films (LB-films) consist from few LB-monolayers which are high structured nanomaterials that are very promising materials for applications. We use a geometrical a…
A new approach to electromagnetism in anisotropic spaces
Nicoleta Voicu-Brinzei, Sergey Siparov
Anisotropy of a space naturally leads to direction dependent electromagnetic tensors and electromagnetic potentials. Starting from this idea and using variational approaches and ex…
