    On construction of darboux integrable discrete models
    (Elsevier Ltd, 2023-12) Zheltukhin, Kostyantyn; Zheltukhina, Natalya
    The problem of discretization of Darboux integrable equations is considered. Given a Darboux integrable continuous equation, one can obtain a Darboux integrable differential-discrete equation, using the integrals of the continuous equation. In the present paper, the discretization of the differential-discrete equations is done using the corresponding characteristic algebras. New examples of integrable discrete equations are obtained.
