This paper defines an operation on the rational points of conic curves C_n(a,b) over the residue class ring Z_n. This operation is called addtion forces C_n(a,b) into a finite abelian group.是什么意思_This paper defines an operation on the rational points of conic curves C_n(a,b) over the residue class ring Z_n.
