Scattering and inverse scattering for a leftdefinite SturmLiouville problem
(2012) In Journal of Differential Equations 253(8). p.23802419 Abstract
 This work develops a scattering and an inverse scattering theory for the SturmLiouville equation u '' qu = lambda wu where w may change sign but q >= 0. Thus the lefthand side of the equation gives rise to a positive quadratic form and one is led to a leftdefinite spectral problem. The crucial ingredient of the approach is a generalized transform built on the Jost solutions of the problem and hence termed the Jost transform and the associated PaleyWiener theorem linking growth properties of transforms with support properties of functions. One motivation for this investigation comes from the CamassaHolm equation for which the solution of the Cauchy problem can be achieved by the inverse scattering transform for u '' + 1/4 u =... (More)
