T.2016-02-082016-02-0820121747-6933http://hdl.handle.net/11693/21461We show that Drury's proof of the generalisation of the von Neumann inequality to the case of contractive rows of N-tuples of commuting operators still holds in the quaternionic case. The arguments require a seemingly new result on tensor products of quaternionic Hilbert spaces. © 2012 Copyright Taylor and Francis Group, LLC.EnglishDrury-Arveson spaceQuaternionic Hilbert spacesReproducing kernel Hilbert spacesTensor productsVon Neumann inequalityPrimary 47A60Secondary 46A3247B3247S10Article10.1080/17476933.2010.5341411747-6941
