Webevery extension of a fully Hilbertian (or Hilbertian) ﬁeld is Hilbertian. For example, a separably closed ﬁeld is not Hilbertian, and hence not fully Hilbertian. The most general result for Hilbertian ﬁelds is Haran’s diamond theorem [10]. We prove an analog of the diamond theorem, and all other permanence criteria for fully Hilbertian ...

WebJan 12, 2011 · The Hilbertian position differs because it depends on a distinction within mathematical language between a finitary sector, whose sentences express contentful propositions, and an ideal, or infinitary sector. Where exactly Hilbert drew the distinction, or where it should be drawn, is a matter of debate. Crucially, though, Hilbert adopted an ... Two Hilbert spaces H1 and H2 can be combined into another Hilbert space, called the (orthogonal) direct sum, and denoted consisting of the set of all ordered pairs (x1, x2) where xi ∈ Hi, i = 1, 2, and inner product defined by More generally, if Hi is a family of Hilbert spaces indexed by i ∈ I, then the direct sum of the Hi, denoted
