A Note on an Asymptotically Good Tame Tower
Siman Yang
The explicit construction of function fields tower with many rational points relative to the genus in the tower play a key role for the construction of asymptotically good algebrai…

Improvement on Parameters of Algebraic-Geometry Codes from Hermitian Curves
Siman Yang
Motivated by Xing's method [7], we show that there exist [n,k,d] linear Hermitian codes over F_{q^2} with k+d>=n-3 for all sufficiently large q. This improves the asymptotic bound…
