Kernel theorems for Beurling-Bj\"orck type spaces

Abstract

We prove new kernel theorems for a general class of Beurling-Bj\"orck type spaces. In particular, our results cover the classical Beurling-Bj\"orck spaces $\S^{(\omega)}_{(\eta)}$ and $\S^{\{\omega\}}_{\{\eta\}}$ defined via weight functions $\omega$ and $\eta$.Comment: 17 page
