Set-theoretic complete intersection monomial curves in affine four space

[摘要] Let C be a monomial curve in affine four space defined by natural numbers n(1), n(2), n(3) and n(4.) We prove that C is a set-theoretic complete intersection, if the least number of n(1), n(2), n(3), n(4) is less than or equal to 13. (C) 2012 Elsevier Inc. All rights reserved.
