extending truncated Barsotti-Tate group
I haved see Illusie's paper, it is true even in some affine case ($X$ is affine ), but I think it may has obstruction in case of smooth projective curve. |

@Mikhail: I mean the maximal commutative subalgebras of endomorpisms of the corresponding abelian varieties of CM-type. |

@Mikhail: In my notation E is just your Z, and The PEL type shimura variety I mentioned is exactly the "auxiliary Shimura variety of PEL-type". And My question is about the CM-point of this "auxiliary Shimura variety of PEL-type", In fact I even wonder is there any classification of CM-fields for given PEL-type shimura datum. |

Diferent abelian varieties over local field with the same p-adic representation?
So if we require that these two Abelian varieties are ordinary, then the answer will be no ? |

I understand know, thank you for your help! |

global section of vector bundle and reduction
And in your counterexample , $H_1$ is a linebundle, of course locally free, and $H_0=\mathcal{O}_{C_0}$ is even free. Do I misunderstanding? |

But if I am not misunderstanding, you mean $H_0$ and $H_1$ (which are vector bundles) locally free but not $H^0$ and $H^1$ (which are cohomology functor). |
