Matrix differential equations and scalar polynomials satisfying higher order recursions

Antonio J. Duran, F. Alberto Grünbaum

We show that any scalar differential operator with a family of polyno- mials as its common eigenfunctions leads canonically to a matrix differen- tial operator with the same proper…

The Rahman Polynomials Are Bispectral

F. Alberto Grünbaum

In a very recent paper, M. Rahman introduced a remarkable family of polynomials in two variables as the eigenfunctions of the transition matrix for a nontrivial Markov chain due to…

Mixed norm estimates for certain generalized Radon transforms

Michael Christ, M. Burak Erdogan

In this paper we investigate the mapping properties in Lebesgue-type spaces of certain generalized Radon transforms defined by integration over curves.

Finite bounds for Holder-Brascamp-Lieb multilinear inequalities

Jonathan Bennett, Anthony Carbery, Michael Christ +1

A criterion is established for the validity of multilinear inequalities of a class considered by Brascamp and Lieb, generalizing well-known inequalities of Holder, Young, and Loomi…

On multilinear oscillatory integrals, nonsingular and singular

Michael Christ, Xiaochun Li, Terence Tao +1

Basic questions concerning nonsingular multilinear operators with oscillatory factors are posed and partially answered. Lebesgue space norm inequalities are established for multili…
