    The dual spaces of martingale Hardy-Lorentz spaces (English)
    0 references
    Using atomic decomposition, the author characterizes the dual spaces of martingale Hardy-Lorentz spaces \(H_{p,q}^s\) as the Lipschitz spaces \(\Lambda_2(\alpha)\), where \(0<p<1\), \(0<q\leq 1\) and \(\alpha=1/p-1\). In this paper, some earlier results (see, e.g. [\textit{C. E. M. Pearce} et al., Numer. Algebra Control Optim. 2, No. 2, 333--355 (2012; Zbl 1274.60134)]) are generalized.
