Hilbert's set
WebNov 22, 2014 · An orthonormal subset of a Hilbert space is closed. In Rudin Real and Complex Analysis there is an exercise (6, Ch. 4) that asks to show that a countably infinite orthonormal set { u n: n ∈ N } in a Hilbert space H is closed and bounded but not compact. That it is bounded and not compact is easy, but I really can't figure out why it is ... WebHilbert space A Hilbert space is a complete inner-product space. An inner-product space can always be \completed" to a Hilbert space by adding the limits of its Cauchy sequences to the space. Examples The most common examples of Hilbert spaces are 1. Euclidean Rn and Cn with inner products de ned by the dot-product hx;yi= P i x iy i. 2.

WebCorollary. If Ais a nonempty closed convex set in a Hilbert space and x∈ X, then ∃ a unique closest element of Ato x. Proof. Let zbe the unique smallest element of the nonempty closed convex set A− x= {y−x: y∈ A}, and let y= z+x. Then y∈ Ais clearly the unique closest element of Ato x.

WebFeb 22, 2024 · $\begingroup$ Also, a Hilbert space is a very special kind of vector space and it doesn't really work to think about it in terms of physical space, i.e. a place that you can be in and walk around in. A mathematical space isn't that at all. The words we use to describe these things mean different things than they do in language. A space in mathematics isn't …
