Weighted spectral cluster bounds and a sharp multiplier theorem for ultraspherical Grushin operators

Valentina Casarino, Paolo Ciatti, Alessio Martini

We study degenerate elliptic operators of Grushin type on the $d$ -dimensional sphere, which are singular on a $k$ -dimensional sphere for some $k < d$ . For these operators we prove…

Uniform pointwise estimates for ultraspherical polynomials

Valentina Casarino, Paolo Ciatti, Alessio Martini

We prove pointwise bounds for two-parameter families of Jacobi polynomials. Our bounds imply estimates for a class of functions arising from the spectral analysis of distinguished…
