摘要: A generalized version of the Hirota's equation with linear inhomogeneities is shown to be equivalent a continuum Heisenberg ferromagnetic spin chain as well Wadati-Konno-Ichikawa-Shimizu (WKIS) type equation, both from geometrical and gauge considerations. The corresponding spectral problems are associated moving eigenvalues.
