与双线性超几何方程相关的电荷可积动力学

Integrable Dynamics of Charges Related to Bilinear Hypergeometric Equation

Igor Loutsenko

摘要:

本文考虑复平面上多项式根的线性和双线性演化的系统族。限制到线,演化诱导库仑电荷在外部电位的动力学,而其不动点对应于平衡的电荷(或点涡流体动力学)在平面上。该构造揭示了与Calogero-Moser系统和李代数微分算子理论的直接联系。研究了经典正交多项式和Adler-Moser多项式代表某些特殊情况的双线性超几何方程的平衡位形

英文摘要:

A family of systems related to a linear and bilinear evolution of roots of polynomials in the complex plane is considered. Restricted to the line, the evolution induces dynamics of the Coulomb charges in external potentials, while its fixed points correspond to equilibria of charges (or point vortices in hydrodynamics) in the plane. The construction reveals a direct connection with the theories of the Calogero-Moser systems and Lie-algebraic differential operators. A study of the equilibrium configurations amounts in a construction (bilinear hypergeometric equation) for which the classical orthogonal and the Adler-Moser polynomials represent some particular cases
