This volume is a compilation of lectures on algebras and combinatorics presented at the Second International Congress in Algebra and Combinatorics. It reports on not only new results, but also on open problems in the field. The proceedings volume is useful for graduate students and researchers in algebras and combinatorics. The contributors include eminent figures such as E Bannai, P Hilton, M Jambu, I Kotsireas, B Schein and A Smoktunowicz.
