Hilbert's set
WebIntroduction I My talk today is on Hilbert’s Nullstellensatz, a foundational result in the eld of algebraic geometry. I First proved by David Hilbert in 1900. I Pronounced \nool-shtell-en-zatss". I The Nullstellensatz derives its name, like many other German words, from a combination of smaller words: null (zero), stellen (to put/place), satz (theorem).

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.
