摘要
We construct g independent (integral) elements in the kernel of the tame symbol on several families of curves with genus g = 1, 2, 4, 7. Furthermore, we prove that there exist non-torsion divisors P - Q with P, Q in the divisorial support of these K-2 elements when g = 1, 2, which is potentially different from previous constructions.
