Abstract

We show that Lubin--Tate theories attached to algebraically closed fields are characterized among T(n)T(n)-local E∞\mathbb{E}_{\infty}-rings as those that satisfy an analogue of Hilbert's Nullstellensatz. Furthermore, we show that for every T(n)T(n)-local E∞\mathbb{E}_{\infty}-ring RR, the collection of E∞\mathbb{E}_\infty-ring maps from RR to such Lubin-Tate theories jointly detect nilpotence. In particular, we deduce that every non-zero T(n)T(n)-local E∞\mathbb{E}_{\infty}-ring RR admits an E∞\mathbb{E}_\infty-ring map to such a Lubin-Tate theory. As consequences, we construct E∞\mathbb{E}_{\infty} complex orientations of algebraically closed Lubin-Tate theories, compute the strict Picard spectra of such Lubin-Tate theories, and prove redshift for the algebraic K\mathrm{K}-theory of arbitrary E∞\mathbb{E}_{\infty}-rings.
