Gauss Integral


Consider two closed oriented space curves f_1:C_1->R^3 and f_2:C_2->R^3, where C_1 and C_2 are distinct circles, f_1 and f_2 are differentiable C^1 functions, and f_1(C_1) and f_2(C_2) are disjoint loci. Let Lk(f_1,f_2) be the linking number of the two curves, then the Gauss integral is

 Lk(f_1,f_2)=1/(4pi)int_(C_1×C_2)dS.
