Abstract:

For $0<p<1$ we describe the dual spaces and Banach envelopes of the spaces $H^{p,q}$ for finite values of $q$ and for $H_{0}^{p,\infty }$, the closure of the polynomials in $H^{p,\infty }$. In addition, we determine the $s$-Banach envelopes for the spaces $H^{p,q}$ in the cases $0<q<p<s\leq 1$ and $0<q<p\leq s\leq 1$.
