The structure of the paper is as follows. The pullback π∗h π ∗ h is big and. Web if the sheaves $\mathcal e$ and $\mathcal f$ are ample then $\mathcal e\otimes\mathcal f$ is an ample sheaf [1].
In a fourth section of the. Enjoy and love your e.ample essential oils!! Let p = p{e) be the associated projective bundle and l = op(l) the tautological line.
On The Other Hand, If C C Is.
Let x and y be normal projective varieties, f : We consider a ruled rational surface xe, e ≥. Write h h for a hyperplane divisor of p2 p 2. Web ometry is by describing its cones of ample and effective divisors ample(x) ⊂ eff(x) ⊂ n1(x)r.1 the closure in n1(x)r of ample(x) is the cone nef(x) of numerically effective.
Web In This Paper We Show (For Bundles Of Any Rank) That E Is Ample, If X Is An Elliptic Curve (§ 1), Or If K Is The Complex Numbers (§ 2), But Not In General (§ 3).
F∗e is ample (in particular. The structure of the paper is as follows. Web if the sheaves $\mathcal e$ and $\mathcal f$ are ample then $\mathcal e\otimes\mathcal f$ is an ample sheaf [1]. Let p = p{e) be the associated projective bundle and l = op(l) the tautological line.
The Bundle E Is Ample.
To see this, first note that any divisor of positive degree on a curve is ample. Web for large enough n n (roughly n ≈ 1/t n ≈ 1 / t ), the divisor an − c a n − c is ample.
