Geometry of quadrilateral nets: second Hamiltonian form
arXiv:0809.1695 · doi:10.1016/j.geomphys.2009.05.003
Abstract
Discrete Darboux-Manakov-Zakharov systems possess two distinct Hamiltonian forms. In the framework of discrete-differential geometry one Hamiltonian form appears in a geometry of circular net. In this paper a geometry of second form is identified.
