BTW, I am not sure it makes to say that some object is "Waelbroeck, as a Banach space". It is a rather subtle consequence of Sakai's theorem/proof that in the isometric sense, there is only one way for a von Neumann algebra to be Waelbroeck: that is, the underlying Banach space of a $W^\ast$-algebra has a unique isometric predual. | |

| Oct 23, 2012 at 13:39 | comment | added | Yemon Choi | Call me grumpy, but I can't help feeling Sakai's name should be mentioned in the last para, even if the words "dual Banach space" are for some reason being avoided. (And yes, I have read that section and others of Cigler-Losert-Michor) | |
