摘要
对于 n 个顶点上的任何树,我们都会关联一个具有 \(3n-2\) 个参数的 n 维 Lotka-Volterra 系统,并且对于参数的一般值,证明它是超可integrable 的,即它允许 \(n-1\) 个函数独立的积分。我们还展示了如何将每个系统还原为一个(\(n-1\))维系统,该系统是超可解的,并且可以通过二次函数求解。
To any tree on n vertices we associate an n-dimensional Lotka–Volterra system with \(3n-2\) parameters and, for generic values of the parameters, prove it is superintegrable, i.e. it admits \(n-1\) functionally independent integrals. We also show how each system can be reduced to an (\(n-1\))-dimensional system which is superintegrable and solvable by quadratures.
期刊介绍:
MPAG is a peer-reviewed journal organized in sections. Each section is editorially independent and provides a high forum for research articles in the respective areas.
The entire editorial board commits itself to combine the requirements of an accurate and fast refereeing process.
The section on Probability and Statistical Physics focuses on probabilistic models and spatial stochastic processes arising in statistical physics. Examples include: interacting particle systems, non-equilibrium statistical mechanics, integrable probability, random graphs and percolation, critical phenomena and conformal theories. Applications of probability theory and statistical physics to other areas of mathematics, such as analysis (stochastic pde''s), random geometry, combinatorial aspects are also addressed.
The section on Quantum Theory publishes research papers on developments in geometry, probability and analysis that are relevant to quantum theory. Topics that are covered in this section include: classical and algebraic quantum field theories, deformation and geometric quantisation, index theory, Lie algebras and Hopf algebras, non-commutative geometry, spectral theory for quantum systems, disordered quantum systems (Anderson localization, quantum diffusion), many-body quantum physics with applications to condensed matter theory, partial differential equations emerging from quantum theory, quantum lattice systems, topological phases of matter, equilibrium and non-equilibrium quantum statistical mechanics, multiscale analysis, rigorous renormalisation group.
