Abstract

The article studies a class of integrable semidiscrete equations with one continuous and two discrete independent variables. Miura type transformations are obtained that relate the equations of the class. A new integrable chain of this type is found, for which the Lax pair is presented. Integrable in the sense of Darboux reductions of the chain are discussed, for small order reductions complete sets of integrals are constructed. Continuum limits for the chain are discussed. A method for finding particular solutions of chains based on integrable in sense of Darboux reductions is proposed. The effectiveness of the method is illustrated by an example.
