Classification of the conditionally observable spectra exhibiting central symmetry
Jun-Hua Chen, Edita Pelantova, Miloslav Znojil
We show how in PT-symmetric 2J-level quantum systems the assumption of an upside-down symmetry (or duality) of their spectra simplifies their classification based on the non-equiva…

The fine gradings of sl(3,C) and their symmetries
M. Havlicek, J. Patera, E. Pelantova +1
We describe the normalizers for all non-conjugate maximal Abelian subgroups of diagonalizable automorphisms of sl(3,C) and show their relation to the symmetries of equations relate…
