It was discovered by David Hilbert while he was struggling with Cantor's set theory. According to Hilbert, it initiated Ernst Zermelo's version of the Zermelo–Russell paradox. It is the paradox of all sets derived from addition (union) and self-mapping. dictionary key 2つ

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.
