Darboux tranformation and solutions of some integrable systems
  The relation between the Darboux transformation and the solutions of the full Kostant Toda lattice is analyzed. The discrete Korteweg de Vries equation is used to obtain such solutions and the main result of [1] is extended to the case of general (p + 2)-banded Hessenberg matrices.
