Castelnuovo-Mumford regularity of seminormal simplicial affine semigroup rings

  title={Castelnuovo-Mumford regularity of seminormal simplicial affine semigroup rings},
  author={Max J. Nitsche},
We show that the Eisenbud-Goto conjecture holds for seminormal simplicial affine semigroup rings. Moreover we prove an upper bound for the Castelnuovo-Mumford regularity in terms of the dimension, which is similar as in the normal case. Finally we compute explicitly the regularity of full Veronese rings.
