Raynaud vector bundles

چکیده
We construct vector bundles Rrk μ on a smooth projective curve X having the property that for all sheaves E of slope μ and rank rk on X we have an equivalence: E is a semistable vector bundle ⇐⇒ Hom(Rrk μ , E) = 0. As a byproduct of our construction we obtain effective bounds on r such that the linear system |R ·Θ| has base points on UX(r, r(g − 1)).

We study base points of the generalized Θ-divisor on the moduli space of vector bundles on a smooth algebraic curve X of genus g defined over an algebraically closed field. To do so, we use the derived categories Db(Pic(X)) and Db(Jac(X)) and the equivalence between them given by the Fourier-Mukai transform FMP coming from the Poincaré bundle. The vector bundles Pm on the curve X defined by Ray...

متن کاملParabolic Raynaud Bundles
Let X be an irreducible smooth projective curve defined over complex numbers, S = {p1, p2, . . . , pn} ⊂ X a finite set of closed points and N ≥ 2 a fixed integer. For any pair (r, d) ∈ N × 1 N Z, there exists a parabolic vector bundle Rr,d,∗ on X , with parabolic structure over S and all parabolic weights in 1 N Z, that has the following property: Take any parabolic vector bundle E∗ of rank r ...
متن کاملTheta divisors and the Frobenius morphism
We introduce theta divisors for vector bundles and relate them to the ordinariness of curves in characteristic p > 0. We prove, following M. Raynaud, that the sheaf of locally exact differentials in characteristic p > 0 has a theta divisor, and that the generic curve in (any) genus g ≥ 2 and (any) characteristic p > 0 has a cover that is not ordinary (and which we explicitely construct). 1 Thet...
متن کاملEquations defining a space curve
Let C ⊂ P be a smooth irreducible complete algebraic curve of degree d embedded in a projective 3-space over an algebraically closed field k. It is called n-regular if H(IC(n− 1)) = H(IC(n− 2)) = 0, where IC is the ideal sheaf of C. Among all this implies that the homogeneous ideal IC = ⊕ l H (IC(l)) ⊂ k[x0, x1, x2, x3] is generated in degree ≤ n ([7], Lecture 14) and C ⊂ P is (scheme-theoretic...
