Noncommutative ampleness for multiple divisors
Dennis S. Keeler
The twisted homogeneous coordinate ring is one of the basic constructions of the noncommutative projective geometry of Artin, Van den Bergh, and others. Chan generalized this const…
The rings of noncommutative projective geometry
Dennis S. Keeler
In the past 15 years a study of ``noncommutative projective geometry'' has flourished. By using and generalizing techniques of commutative projective geometry, one can study certai…
Frobenius amplitude and strong vanishing theorems for vector bundles
Donu Arapura, Dennis S. Keeler
The primary goal of this paper is to systematically exploit the method of Deligne-Illusie to obtain Kodaira type vanishing theorems for vector bundles and more generally coherent s…
Criteria for σ-ampleness
Dennis S. Keeler
In the noncommutative geometry of Artin, Van den Bergh, and others, the twisted homogeneous coordinate ring is one of the basic constructions. Such a ring is defined by a -ample…
