Integral models in unramified mixed characteristic \((0,2)\) of Hermitian orthogonal Shimura varieties of PEL type. II. (English) Zbl 1305.11056
The paper under review is a continuation of an earlier work [J. Ramanujan Math. Soc. 27, No. 4, 425–477 (2012; Zbl 1357.11062)] of the author. Its main goal is to prove the existence of integral canonical models of the so-called hermitian orthogonal Shimura varieties of PEL type in unramified mixed characteristic \((0,2)\). These PEL Shimura varieties are moduli spaces of polarized abelian schemes equipped with a suitable endomorphism algebra and level structure. The method in the paper is somehow standard – to prove the regularity and formal smoothness of the normalization of the schematic closure of a natural subscheme; however the technique is of high level.
