Weierstrass Semigroups From a Tower of Function Fields Attaining the Drinfeld-Vladut Bound
Shudi Yang, Chuangqiang Hu
For applications in algebraic geometric codes, an explicit description of bases of Riemann-Roch spaces of divisors on function fields over finite fields is needed. We investigate t…

Complete Weight Distribution and MacWilliams Identities for Asymmetric Quantum Codes
Chuangqiang Hu, Shudi Yang, Stephen S. -T. Yau
In 1997, Shor and Laflamme defined the weight enumerators for quantum error-correcting codes and derived a MacWilliams identity. We extend their work by introducing our double weig…
