Continuous Symmetries of Difference Equations
Lie group theory was originally created more than 100 years ago as a tool for solving ordinary and partial differential equations. In this article we review the results of a much more recent program: the use of Lie groups to study difference equations. We show that the mismatch between continuous symmetries and discrete equations can be resolved in at least two manners. One is to use generalize...
متن کاملPartial Symmetries in Nuclear Models
This method leads to decomposition of nuclear spectra not into traditional bands constructed by hands, using as the main criterion the strongest E2 transitions, but to a decomposition in respect to symmetries: each band correspond to a given symmetry with all consequences caused by the corresponding selection rules and similar relations like level degenerations correlated to dimensions of irred...
متن کاملFinite symmetries in epidemic models
We present an algorithm which explores permutation symmetries to describe the time evolution of agent-based epidemic models. The main idea to improve computation times relies on restricting the stochastic process to one sector of the vector space, labeled by a single permutation eigenvalue. In this scheme, the transition matrix reduces to block diagonal form, enhancing computational performance...
متن کاملSuperconformal Symmetries and Models
We discuss the following aspects of two-dimensional N = 2 supersymmetric theories defined on compact super Riemann surfaces: parametrization of (2, 0) and (2, 2) superconformal structures in terms of Beltrami coefficients and formulation of superconformal models on such surfaces (invariant actions, anomalies and compensating actions, Ward identities).
متن کاملLarge Lepton Mixings from Continuous Symmetries
Within the broad context of quark-lepton unification, we investigate the implications of broken continuous family symmetries which result from requiring that in the limit of exact symmetry, the Dirac mass matrices yield hierarchical masses for the quarks and charged leptons, but lead to degenerate light neutrino masses as a consequence of the seesaw mechanism, without requiring hierarchical rig...
