Abstract

Let OK\mathcal{O}_{K} be a complete discrete valuation ring of mixed characteristic with perfect residue field, endowed with its canonical log-structure. We prove that log pp-divisible groups over OK\mathcal{O}_{K} correspond to Dieudonn\'e crystals on the absolute log-prismatic site of OK\mathcal{O}_{K} endowed with the Kummer log-flat topology. The proof uses log-descent to reduce the problem to the classical prismatic correspondence, recently established by Ansch\"utz-Le Bras.
