Integrable boundary conditions for the Hirota-Miwa equation and Lie algebras
Ismagil Habibullin, Aigul Khakimova
Systems of discrete equations on a quadrilateral graph related to the series of the affine Lie algebras are studied. The systems are derived from the Hirota-Miwa equati…

Discrete exponential type systems on a quad graph, corresponding to the affine Lie algebras
I T Habibullin, A R Khakimova
The article deals with the problem of the integrable discretization of the well-known Drinfeld-Sokolov hierarchies related to the Kac-Moody algebras. A class of discrete exponentia…
