The conference " Coding Theory " intended to be a platform where the rather inhomo-geneous coding community could exchange ideas. Both the engineers could present their mathematical problems and the mathematicians could report their progress. The result was a lively meeting with an open exchange of ideas and lots of discussion.

As pointed out in Arbarello and Cornalba (J. Alg. Geom. 5 (1996), 705–749), a theorem due to Di Francesco, Itzykson, and Zuber (see Di Francesco, Itzykson, and Zuber, Commun. Math. Phys. 151 (1993), 193–219) should yield new relations among cohomology classes of the moduli space of pointed curves. The coefficients appearing in these new relations can be(More)
