The AAECC conferences focus on the algebraic aspects of
modern computer science, which includes the most up-to-date
and advanced topics. The topic of error-correcting codes is
one where theory and implementation are unifiedinto a
subject both of mathematical beauty and of practical
importance. Algebraic algorithms are not only interesting
theoretically but also important in computer and
communication engineering and many other fields.
This volume contains the proceedings of the 9th AAECC
conference, held in New Orleans, LA, in October 1991.
Researchers from Europe, America, Japan and other regions of
the world presented papers at the conference. The papers
present new results of recent theoretical and
application-oriented research in the field.
