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. Web2.

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).
