diagonal map; holomorphic function; Bergman space; polydisk
Summary:
For any holomorphic function $f$ on the unit polydisk $\mathbb D ^n$ we consider its restriction to the diagonal, i.e., the function in the unit disc $\mathbb D \subset \mathbb C $ defined by $\mathop{\rm Diag} f(z)=f(z,\ldots ,z)$, and prove that the diagonal map ${\rm Diag}$ maps the space $Q_{p,q,s}(\mathbb D ^n)$ of the polydisk onto the space $\widehat Q^q_{p,s,n}(\mathbb D )$ of the unit disk.
