Bogomolov-Sommese vanishing and liftability for surface pairs in positive characteristic
نویسندگان
چکیده
We show that the Bogomolov-Sommese vanishing theorem holds for a log canonical projective surface (X,B) in large characteristic unless Iitaka dimension of KX+?B? is not equal to two. As an application, we prove resolution pair normal and reduced divisor lifts ring Witt vectors when less than or zero. Moreover, give explicit optimal bounds on their dimensions are

Surfaces Violating Bogomolov-miyaoka-yau in Positive Characteristic
The Bogomolov-Miyaoka-Yau inequality asserts that the Chern numbers of a surface X of general type in characteristic 0 satisfy the inequality c1 ≤ 3c2, a consequence of which is K2 X χ(OX ) ≤ 9. This inequality fails in characteristic p, and here we produce infinite families of counterexamples for large p. Our method parallels a construction of Hirzebruch, and relies on a construction of abelia...
متن کاملA vanishing theorem for Fano varieties in positive characteristic
for i < d, where WΩdX is the sheaf of De Rham-Witt (DRW) differential forms of degree d constructed by Bloch and Illusie. This is because H(WOX)⊗K is the part of crystalline cohomology with Frobenius slopes in the interval [0, 1[, while Hi(W,WΩdX) is the part with slope d ([9] cor. II.3.5). The author gave an erroneous proof of this corollary (in fact, an integral version) in an earlier preprin...
متن کاملEffective Non-vanishing for Algebraic Surfaces in Positive Characteristic
We give a partial answer to the effective non-vanishing problem for algebraic surfaces in positive characteristic, and also give counterexamples for the Kawamata-Viehweg vanishing and the logarithmic semipositivity on ruled surfaces in positive characteristic.

متن کاملThere Is No Bogomolov Type Restriction Theorem for Strong Semistability in Positive Characteristic
We give an example of a strongly semistable vector bundle of rank two on the projective plane such that there exist smooth curves of arbitrary high degree with the property that the restriction of the bundle to the curve is not strongly semistable anymore. This shows that a Bogomolov type restriction theorem does not hold for strong semistability in positive characteristic. Mathematical Subject...
