标题： On Calogero-Francoise-type Lax matrices and their dynamical r-matrices

摘要： 新的经典可积的Camassa-Holm尖峰子型系统被提出。 它们实现了Calogero-Francoise流的最大偶数分段-D_2推广，产生周期性和准周期性三角/双曲势。 计算了相关的r-矩阵。 它们是动态的，并依赖于两组规范变量{p_i}和{q_i}。 显示英文摘要

摘要： New classical integrable systems of Camassa-Holm peakon type are proposed. They realize the maximal even piecewise-D_2 generalization of the Calogero-Francoise flows, yielding periodic and pseudoperiodic trigonometric/hyperbolic potentials. The associated r-matrices are computed. They are dynamical and depend on both sets {p_i} and {q_i} of canonical variables.
