متن کاملOn Non-vanishing of Cohomologies of Generalized Raynaud Polarized Surfaces
We consider a family of slightly extended version of the Raynaud’s surfaces X over the field of positive characteristic with Mumford-Szpiro type polarizations Z, which have Kodaira non-vanishing H(X,Z) 6= 0. The surfaces are at least normal but smooth under a special condition. We compute the cohomologies H(X,Z) for i, n ∈ Z and study their (non-)vanishing. Finally, we give a fairly large famil...
متن کاملKawamata-Viehweg Vanishing on Rational Surfaces in Positive Characteristic
We prove that the Kawamata-Viehweg vanishing theorem holds on rational surfaces in positive characteristic by means of the lifting property to W2(k) of certain log pairs on smooth rational surfaces. As a corollary, the Kawamata-Viehweg vanishing theorem holds on log del Pezzo surfaces in positive characteristic.
متن کاملRims-1736 Counterexamples of Kodaira’s Vanishing and Yau’s Inequality in Positive Characteristics
We generalize Tango’s theorem [T1] on the Frobenius map of the first cohomology groups to higher dimensional algebraic varieties in characteristic p > 0. As application we construct counterexamples of Kodaira vanishing in higher dimension, and prove the Ramanujam type vanishing on a surface which is not of general type when p ≥ 5. Let X be a smooth complete algebraic variety over an algebraical...

Using methods from the modular representation theory of algebraic groups one can construct [1] a projective homogeneous space for SL 4 in prime characteristic , which violates Kodaira vanishing. In this note we show how elementary algebraic geometry can be used to simplify and generalize this example. Let X be a smooth projective variety of dimension m over an algebraically closed field of char...
