RETRACTED ARTICLE: Conditional expectations in \(L^p(\mu ;L^q(\nu ;X))\)
The authors have retracted this article  because of an error in the proof of the first lemma. The gap in the proof has the effect that the main result is incorrect and this affects all other results in the paper. Both authors agree to this retraction.
