Abstract
The most important uniform algebra is the family of continuous functions on a compact subset of the complex plane \mathbb C which are analytic on the interior {\rm int} (K). For polyanalytic functions and compact sets K which are regular (i.e. K=\overline {{\rm int} (K)}), we introduce analogous spaces, which are Banach spaces with respect to the sup-norm, but are not closed with respect to the usual pointwise multiplication. We introduce a multiplication on these spaces and investigate the resulting algebras.
