Generalized symmetries and integrability conditions for hyperbolic type semi-discrete equations
Rustem N. Garifullin, Ismagil T. Habibullin
In the article differential-difference (semi-discrete) lattices of hyperbolic type are investigated from the integrability viewpoint. More precisely we concentrate on a method for…

Modified series of integrable discrete equations on a square lattice with a non-standard symmetry structure
R. N. Garifullin, R. I. Yamilov
In a recent paper [TMP, 200:1 (2019), 966--984] by the authors, a series of integrable discrete autonomous equations on a square lattice with a non-standard structure of generalize…
