Hernández-Bermejo, Benito; Brenig, Léon Characterization and solvability of quasipolynomial symplectic mappings. (English) Zbl 1040.37036 J. Phys. A, Math. Gen. 37, No. 6, 2191-2200 (2004). Summary: Quasipolynomial (or QP) mappings constitute a wide generalization of the well-known Lotka-Volterra mappings, which are of importance in different fields such as population dynamics, physics, chemistry or economy. In addition, QP mappings are a natural discrete-time analogue of the continuous QP systems, which have been extensively used in different pure and applied domains. After presenting the basic definitions and properties of QP mappings in a previous paper [the authors, J. Phys. A, Math. Gen. 35, 5453–5469 (2002; Zbl 1039.37010)], the purpose of this work is to focus on their characterization by considering the existence of symplectic QP mappings. In what follows, such QP symplectic maps are completely characterized. Moreover, use of the QP formalism can be made in order to demonstrate that all QP symplectic mappings have an analytical solution that is explicitly and generally constructed. Examples are given.
