Exceptional orthogonal polynomials and the Darboux transformation [PDF]

, 2010
We adapt the notion of the Darboux transformation to the context of polynomial Sturm-Liouville problems. As an application, we characterize the recently described $X_m$ Laguerre polynomials in terms of an isospectral Darboux transformation.

Nonparametric joint shape learning for customized shape modeling [PDF]

, 2010
We present a shape optimization approach to compute patient-specific models in customized prototyping applications. We design a coupled shape prior to model the transformation between a related pair of surfaces, using a nonparametric joint probability ...
