摘要:
It is well known that the asymptotic Gilbert-Varshamov bound in coding theory was improved in 1982 by the TVZ bound with the help of algebraic-geometry codes. In recent years, the TVZ bound was improved by using constructions of new types of algebraic-geometry codes. The paper surveys these recent developments and also provides a general introduction to the asymptotic theory of codes.
