The higher-dimensional jet ampleness vanishing conjecture for syzygies
The higher-dimensional jet ampleness vanishing conjecture for syzygies
Let be a smooth projective variety of dimension , let with ample and an arbitrary divisor on , and let be a line bundle on . For the Koszul cohomology group , the conjecture concerns its vanishing for all sufficiently large . Higher-dimensional jet ampleness conjecture. If is -jet very ample, meaning that for every effective zero-cycle of degree , the natural map
is surjective, then
This would give geometric conditions ensuring asymptotic vanishing of the most interesting Koszul cohomology group in higher dimensions. The assertion is presented as a conceivable extension of the curve case, but the supplied text does not establish it.
