Abstract

Given a projective scheme XX over a field kk, an automorphism σ\sigma of XX, and a σ\sigma-ample invertible sheaf LL, one may form the twisted homogeneous coordinate ring B=B(X,L,σ)B = B(X, L, \sigma), one of the most fundamental constructions in noncommutative projective algebraic geometry. We study the primitive spectrum of BB, as well as that of other closely related algebras such as skew and skew-Laurent extensions of commutative algebras. Over an algebraically closed, uncountable field kk of characteristic zero, we prove that that the primitive ideals of BB are characterized by the usual Dixmier-Moeglin conditions whenever the dimension of XX is no more than 2.
