Optimal properties related to Total Positivity and Wronskian matrices [PDF]

open access: yes
B-bases are totally positive bases satisfying several optimal properties. In this paper we prove a new optimal property of B-bases related to the conditioning of their Wronskian ...

THE GENERALIZED WRONSKIAN SOLUTIONS OF THE INTEGRABLE VARIABLE-COEFFICIENT KORTEWEG-DE VRIES EQUATION

open access: yes, 2011
A broad set of sufficient conditions consisting of systems of linear partial differential equations are presented which guarantee that the Wronskian determinant is the solutions of the integrable variable-coefficient Korteweg-de Vries model from Bose ...

Hyperbolic and Weak Euclidean Polynomials from Wronskian and Leibniz Maps

open access: yesAxioms
A real univariate polynomial is called hyperbolic or stable if all its roots are real. We search for hyperbolic polynomials of two and three degrees by using the Wronskian map W and a dual map to W called Leibniz, since it involves the classical Leibniz ...

On Wronskians Whose Elements are Orthogonal Polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1964
where { Qr(x) } (r = 0, 1, 2, * . . ) is a sequence of orthogonal polynomials associated with a certain measure. They proved [1, Theorem 1] if I is even, W(n, 1; x) keeps constant sign for all real x, i.e., the Wronskian (1), which is an n.1 degree polynomial, has only complex roots.

Algebraic approaches to eigenvalue equations: The Wronskian method

open access: yes, 1987
A recently proposed method for the solution of eigenvalue equations is applied to two different model potentials. Considerable improvements are observed if the algebraic requirements of the Wronskian method are enforced over a region instead of at a ...

A second Wronskian formulation of the Boussinesq equation,

open access: yes, 2009
a b s t r a c t A Wronskian formulation leading to rational solutions is presented for the Boussinesq equation. It involves third-order linear partial differential equations, whose representative systems are systematically solved. The resulting solutions

Invertible Darboux Transformations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2013
For operators of many different kinds it has been proved that (generalized) Darboux transformations can be built using so called Wronskian formulae.
