Darboux transformations for q-discretizations of 2D second order differential equations
نویسنده
چکیده
One of the important components of the theory of nonlinear S-integrable differential equations [1] is Darboux transformations, the story of which starts with the paper by Moutard [2] and therefore, contrary to the common tendency, we will call them Moutard-Darboux transformations. An example of an equation which admits Moutard-Darboux transformations is the second order linear differential equation in two independent variables

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 equations. We construct, in particular, the Darboux transformations for the general self ad-joint schemes with five and seven neighbouring points. We also introduce a distinguished discretization of the two-dimension...
متن کاملFractional Darboux Transformations
In this paper we utilize the covariance of Riccati equation with respect to linear fractional transformations to define classes of conformally equivalent second order differential equations. This motivates then the introduction of fractional Darboux transformations which can be recognized also as generalized Cole-Hopf transformations. We apply these transformations to find Schrodinger equations...

It is well known that if a scalar second order hyperbolic partial differential equation in two independent variables is Darboux integrable, then its local Cauchy problem may be solved by ordinary differential equations. In addition, such an equation has infinitely many non-trivial conservation laws. Moreover, Darboux integrable equations have properties in common with infinite dimensional compl...
متن کاملDifferential Transformations of Parabolic Second-Order Operators in the Plane
The theory of transformations for hyperbolic second-order equations in the plane, developed by Darboux, Laplace and Moutard, has many applications in classical differential geometry [12, 13], and beyond it in the theory of integrable systems [14, 19]. These results, which were obtained for the linear case, can be applied to nonlinear Darboux-integrable equations [2, 7, 15, 16]. In the last deca...
متن کاملReduction Operators of Linear Second-Order Parabolic Equations
The reduction operators, i.e., the operators of nonclassical (conditional) symmetry, of (1 + 1)dimensional second order linear parabolic partial differential equations and all the possible reductions of these equations to ordinary differential ones are exhaustively described. This problem proves to be equivalent, in some sense, to solving the initial equations. The “no-go” result is extended to...
