On some algebraic properties of semi-discrete hyperbolic type equations
(Scientific and Technical Research Council of Turkey (TUBITAK), 2008)
Nonlinear semi-discrete equations of the form tx(n + 1) = f(t(n),t(n + 1),tx(n)) are studied. An adequate algebraic formulation of the Darboux integrability is discussed and an attempt to adopt this notion to the classification ...
