### DIMACS Workshop on Codes and Association Schemes

#### November 9 - 12, 1999

DIMACS Center, Rutgers University, Piscataway, NJ

**Organizers:**
** Alexander Barg**, Bell Labs, Lucent Technologies, abarg@research.bell-labs.com
** Simon Litsyn**, Tel Aviv University, litsyn@eng.tau.ac.il

The workshop is of primary interest to mathematicians (coding
theorists, combinatorialists) and also to computer scientists
and engineers.
Applications of algebraic combinatorics, in particular,
theory of association schemes to coding theory
account for most important structural results and
bounds on the size of codes and designs. This link,
understood broadly, will be the main topic of the workshop.
Applications to codes include bounds and properties of
codes in discrete spaces (Hamming space, Johnson space),
packings of lines and other linear spaces in the Euclidean space,
quantum codes, properties of distance enumerators of codes,
constructions of codes.

The workshop will include, but is not limited to the
following topics:

- applications of the polynomial (linear programming) method;
- properties of codes in discrete metric spaces;
- spherical codes, packings of Grassmanians;
- properties of quantum codes;
- classification and properties of association schemes
- properties of orthogonal polynomials (zeros, asymptotics)
- constructions of codes related to the above methods

Talks will be by invitation only. We would like
to limit the number of talks in order to leave time for
interaction of participants. A list of speakers will be
available as the workshop draws nearer.
We intend to put together a volume of Proceedings in the AMS-DIMACS
series. The volume will include original papers on combinatorial
coding theory or surveys written by the participants.
A booklet with abstracts of talks will be distributed at the workshop.
