Query: Soliton solutions in the class of implicit difference schemes   We announce a detailed numerical investigation for some class of difference
schemes, which arises from Euler implicit scheme. Such schemes demonstrate
unusual behavior and leads to origin of solitons. Applications to some
nonlinear problems are discussed.
