Picard groups of quotient ring spectra

Ishan Levy, Guchuan Li, Ningchuan Zhang

We develop tools to study Picard groups of quotients of ring spectra by a finitely generated ideal, which we use to show that $Pic (E_{n} / I) = Z /2$ , where $…

Equivariant algebraic $K$ -theory and Artin $L$ -functions

Elden Elmanto, Ningchuan Zhang

In this paper, we generalize the Quillen-Lichtenbaum Conjecture relating special values of Dedekind zeta functions to algebraic $K$ -groups. The former has been settled by…
