Discrete mappings with an explicit discrete Lyapunov function related to integrable mappings
We propose discrete mappings of second order that have a discrete analogue of Lyapunov function. The mappings are extensions of the integrable Quispel-RobertsThompson (QRT) mapping, and a discrete Lyapunov function of the mappings is identical to an explicit conserved quantity of the QRT mapping. Moreover we can obtain a differential and an ultradiscrete limit of the mappings preserving the exi...
متن کاملIntegrable Quantum Mappings and Quantization Aspects of Integrable Discrete-time Systems
We study a quantum Yang-Baxter structure associated with non-ultralocal lattice models. We discuss the canonical structure of a class of integrable quantum mappings, i.e. canonical transformations preserving the basic commutation relations. As a particular class of solutions we present two examples of quantum mappings associated with the lattice analogues of the KdV and MKdV equations, together...
متن کاملSome explicit formulas of Lyapunov exponents for 3D quadratic mappings
This paper shows that there exist six different cases where it is possible to find rigorously a Lyapunov exponent for 3-D quadratic mappings. An elementary example is also given and discussed.
متن کاملOn data - driven derivation of discrete mappings
The guessing of a function behind a discrete mapping between nite spaces using only the information provided by positive examples is shown to be in principle optimally handled by a lookup table combined with a random process. We explore the implications of this result for the construction of intelligent approximators.
