$(G,\mu)$-displays and Rapoport-Zink spaces

Abstract: Let $(G,\mu)$ be a pair of a reductive group $G$ over the $p$-adic integers and a minuscule cocharacter $\mu$ defined over an unramified extension. We introduce $(G,\mu)$-displays, which generalize Zink's Witt vector displays. We use these to introduce certain Rapoport-Zink formal schemes group theoretically, i.e. without reference to $p$-divisible groups.
