摘要

Let C(n) be a complete intersection monomial curve in the 4-dimensional affine space.In this paper we study the complete intersection property of the monomial curve C(n + wv),where w ＞ 0 is an integer and v ∈ N4.In addition,we investigate the Cohen-Macaulayness of the tangent cone of C(n + wv).
