Singular Lagrangians in supermechanics
José F. Cariñena, Héctor Figueroa
The time evolution operator is introduced in the graded context and its main properties are discussed. In particular, the operator is used to analize the projectability of…
A new geometric approach to Lie systems and physical applications
José F. Cariñena, Arturo Ramos
The characterization of systems of differential equations admitting a superposition function allowing us to write the general solution in terms of any fundamental set of particular…
Simple trace criterion for classification of multilayers
L. L. Sanchez-Soto, J. J. Monzon, T. Yonte +1
The action of any lossless multilayer is described by a transfer matrix that can be factorized in terms of three basic matrices. We introduce a simple trace criterion that classifi…
Understanding multilayers from a geometrical viewpoint
T. Yonte, J. J. Monzon, L. L. Sanchez-Soto +2
We reelaborate on the basic properties of lossless multilayers. We show that the transfer matrices for these multilayers have essentially the same algebraic properties as the Loren…
Contractions: Nijenhuis and Saletan tensors for general algebraic structures
J. F. Carinena, J. Grabowski, G. Marmo
Generalizations in many directions of the contraction procedure for Lie algebras introduced by E.J.Saletan are proposed. Products of arbitrary nature, not necessarily Lie brackets,…
Non-Hermitian oscillator-like Hamiltonians and -coherent states revisited
J. Beckers, J. F. Cariñena, N. Debergh +1
Previous -deformed {\it non-Hermitian} Hamiltonians with respect to the usual scalar product of Hilbert spaces dealing with harmonic oscillator-like developments are (re)conside…
