Twisted sums, Fenchel-Orlicz spaces and property (M)
arXiv:math/9607206
Abstract
We study certain twisted sums of Orlicz spaces with non-trivial type which can be viewed as Fenchel-Orlicz spaces on . We then show that a large class of Fenchel-Orlicz spaces on can be renormed to have property (M). In particular this gives a new construction of the twisted Hilbert space and shows it has property (M), after an appropriate renorming.
