Abstract:
Evolution equations with a pseudodifferential operator associated with the Zakharov–Shabat spectral problem are investigated. Correspondence between their symmetries
and the symmetiies of Schrödinger-type equations is established. This correspondence
is used to construct the soliton solutions.
