Math. 86, 173-247 (1990). [For the entire collection see Zbl 0717.00008; for part I see Astérisque 63, 17-38 (1979; Zbl 0414.14014); part II appeared as book, Lect. Notes Math. 930 (1982; Zbl 0516.14015).]This is the third in the series of papers devoted to Dieudonné crystalline theory. In the paper under review the authors prove some results announced in part I (loc. cit.). The authors study faithfulness properties of the Dieudonné crystalline functor.As an application, the authors show that on a liftable proper smooth simply-connected variety each \(p\)-divisible group is isoconstant, i.e. isogenous to a constant \(p\)-divisible group.
