Geometric discretization of the Bianchi system
A. Doliwa, M. Nieszporski, P. M. Santini
We introduce the dual Koenigs lattices, which are the integrable discrete analogues of conjugate nets with equal tangential invariants, and we find the corresponding reduction of t…
Algebro-geometric solution of the discrete KP equation over a finite field out of a hyperelliptic curve
M. Bialecki, A. Doliwa
We transfer the algebro-geometric method of construction of solutions of the discrete KP equation to the finite field case. We emphasize role of the Jacobian of the underlying alge…
Darboux transformations for 5-point and 7-point self-adjoint schemes and an integrable discretization of the 2D Schrodinger operator
M. Nieszporski, P. M. Santini, A. Doliwa
With this paper we begin an investigation of difference schemes that possess Darboux transformations and can be regarded as natural discretizations of elliptic partial differential…
