<Niko Naumann> works in <arithmetic geometry> and <homotopy theory>. With <Annette Huber> and <Guido Kings>, he refined the <Lazard isomorphism>, extending a comparison between <continuous group cohomology> and <Lie algebra cohomology> to integral coefficients under suitable hypotheses.<Some complements to the Lazard isomorphism by Annette Huber and others>[Abstract and the integral comparison results]{ref}
The distinction between integral and rational coefficients matters: tensoring with $\mathbb Q_p$ can discard <torsion elements>, so a rational comparison does not automatically recover integral information. The same work also treats analytic cochains over finite extensions of $\mathbb Q_p$. Naumann's author page lists arithmetic <algebraic geometry>, motivic <homotopy theory>, and joint work on nilpotence and descent in equivariant <stable homotopy theory>.https://homepages.uni-regensburg.de/~nan25776/[Research and Preprints and publications]{ref}
