Hilbert theorem 94

Web摘要： Let T be a C.(0)-contraction on a Hilbert space H and S be a nontrivial closed subspace of H. We prove that S is a T-invariant subspace of H if and only if there exists a Hilbert space D and a partially isometric operator Pi: H-D(2)(D) -> H such that Pi M-z = T Pi and that S = ran Pi, or equivalently WebThat is, a Hilbert space is an inner product space that is also a Banach space. For example, Rn is a Hilbert space under the usual dot product: hv;wi= v w = v 1w 1 + + v nw n: More generally, a nite-dimensional inner product space is a Hilbert space. The following theorem provides examples of in nite-dimensional Hilbert spaces. Theorem 1 L2 is ...

In such an extension, it is shown that the subgroup of the ideal class group of F which becomes principal in K has order divisible by the degree [K: F]. It is not, in general, known which subgroup becomes principal.
