It is shown that a Banach space E has type p if and only for some (all) d ≥ 1 the Besov space B (1/ p – 1/2) dp , p (ℝ d ; E ) embeds into the space γ ( L 2 (ℝ d ), E ) of γ ‐radonifying operators L 2 (ℝ d ) → E . A similar result characterizing cotype q is obtained. These results may be viewed as E ‐valued extensions of the classical Sobolev embedding theorems. (© 2008 WILEY‐VCH Verlag GmbH & Co.
