Backlund transformation of the Geng-Xue system
Lihua Wu, Nianhua Li
We construct a Backlund transformation for the Geng-Xue system with the help of reciprocal and gauge transformations. Furthermore, we derive N-Backlund transformation for the Geng-…
Geodesic scattering on hyperboloids and Knörrer's map
Alexander Veselov, Lihua Wu
We use the results of Moser and Knörrer on relations between geodesics on quadrics and solutions of the classical Neumann system to describe explicitly the geodesic scattering on h…
Algebro-geometric Constructions to the Dym-type Hierarchy
Lihua Wu, Guoliang He, Xianguo Geng
Resorting to the characteristic polynomial of Lax matrix for the Dym-type hierarchy, we define a trigonal curve, on which appropriate vector-valued Baker-Akhiezer function and mero…
Reciprocal link for a coupled Camassa-Holm type equation
Nianhua Li, Jinshun Zhang, Lihua Wu
A coupled Camassa-Holm type equation is linked to the first negative flow of a modified Drinfeld-Sokolov III hierarchy by a transformation of reciprocal type. Meanwhile the Lax pai…
