Degenerate Sklyanin algebras and generalized twisted homogeneous coordinate rings (vol 322, pg 2508, 2009)

[摘要] There is an error in the computation of the truncated point schemes V-d of the degenerate Sklyanin algebra S(1,1,1). We are grateful to S. Paul Smith for pointing out that V-d is larger than was claimed in Proposition 3.13. All 2 or 3 digit references are to the above paper, while 1 digit references are to the results in this corrigendum. We provide a description of the correct V-d in Proposition 5 below. Results about the corresponding point parameter ring B associated to the schemes {V-d}(d >= 1) are given afterward. (C) 2012 Elsevier Inc. All rights reserved.
