对于具有k>0的互素整数h和k,定义Dedekind符号(h,k)为(h,k,=,,,(h,k,=,k:,:;(;-[;i-;)),其中S(h,k)是Dedekindsum(cf.Hirzebruch和Zagier[Z],Rademacher和Grosswald[4])。此符号为整数值。下列性质是众所周知的:2/2(/z,k)+2k(k,h)=h‘+k2-3hk+1,(1)(h’,k)=(h,k)若h‘zh(Modk),(2)(-h,k)=-(h,k),(3)(h,k)-0,+L,+3(Mod9)。
For coprime integers h and k with k> 0, the Dedekind symbol (h, k) is defined as (h, k,=,,,(h, k,=, k:,:;(;-[; I-;), where s (h, k) is the Dedekind sum (cf. Hirzebruch and Zagier [Z], Rademacher and Grosswald [4]). This symbol is integer-valued. The following properties are well known:2/2 (/z, k)+ 2k (k, h)= h’+ k2-3hk+ 1,(1)(h’, k)=(h, k) if h’zh(modk),(2)(-h, k)=-(h, k),(3)(h, k)-0,+ l,+ 3 (mod9).
