Hilbert's set

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.

WebHilbert Curves are named after the German mathematician David Hilbert. They were first described in 1891. A Hilbert curve is a continuous space-filing curve. They are also fractal and are self-similar; If you zoom in and look closely at a section of a higher-order curve, the pattern you see looks just the same as itself. WebMay 3, 2002 · The epsilon calculus is a logical formalism developed by David Hilbert in the service of his program in the foundations of mathematics.
