On Recursion Operators
We observe that application of a recursion operator of Burgers equation does not produce the expected symmetries. This is explained by the incorrect assumption that D−1 x Dx = 1. We then proceed to give a method to compute the symmetries using the recursion operator as a first order approximation.
متن کاملThe Sums and Products of Commuting AC-Operators
Abstract: In this paper, we exhibit new conditions for the sum of two commuting AC-operators to be again an AC-operator. In particular, this is satisfied on Hilbert space when one of them is a scalar-type spectral operator.
متن کاملAnother Look on Recursion Operators
Recursion operators of partial diierential equations are identiied with BB acklund auto-transformations of linearized diieties. Relations to the classical concept and its recent Guthrie's generalization are discussed. Traditionally,a recursion operator of a PDE is a linear operator L acting on symmetries: if f is a symmetry then so is Lf. This provides a convenient way to generate innnite famil...
متن کاملRecursion Operators and Frobenius Manifolds
In this note I exhibit a “discrete homotopy” which joins the category of Fmanifolds to the category of Poisson–Nijenhuis manifolds, passing through the category of Frobenius manifolds.
