摘要:
We generalize Illusie's result to prove the decomposition of the de Rham complex with smooth horizontal coefficients for a semistable S-morphism f:X->Y which is liftable over Z/p^2 Z. As an application, we prove the Kollar vanishing theorem in positive characteristic for a semistable S-morphism f:X->Y which is liftable over Z/p^2 Z, where all concerned horizontal divisors are smooth over Y.
