Streszczenie
We prove an analogue of Y. Meyer's wavelet characterization of the Hardy space $H^1(\Bbb R^n)$ for the space $H^1(\Bbb R^n,X)$ of $X$-valued functions. Here $X$ is a Banach space with the UMD property. The proof uses results of T. Figiel on generalized Calderón–Zygmund operators on Bochner spaces and some new local estimates.
