Third (Final) Announcement


The Conference Algebraic Combinatorics


It is an annual conference dedicated to the themes in the field of algebraic combinatorics, including association schemes, codes, designs, finite geometry, graphs, and groups. This year´s conference, which is the 23rd of the series, is especially dedicated to the work of Eiichi Bannai in celebration of his 60th birthday. This field has been remarkable growth since 1984 publication of Bannai and Ito´s book, ``Algebraic Combinatorics I: Association Schemes.´´ Research developments on this subject have proceeded at an extraordinary pace in various directions in the last two decades. The goals of the conference are to disseminate some of the recent successes on the subject to the mathematical community, to discuss various emerging mathematical topics for which algebraic and combinatorial techniques are needed, and to bring together Bannai´s associates to celebrate Eiichi´s career.
