内容提要：

The problem of sparse interpolation with arbitrary orthogonal bases can be regarded as a generalization of sparse 

interpolation with the Chebyshev basis. In Lakshman and Saunder [1996], an algorithm, based on Prony/Blahut's method

 is provided to interpolate polynomials that are sparse in the Chebyshev basis (of the first kind). In this talk, we will 

present new algorithms for interpolating a univariate black-box univariate polynomial that has a sparse representation

 by allowing arbitrary orthogonal bases. This is joint work with Erich L. Kaltofen.
