Share this page *Edited by *
*César Polcino Milies*

This book contains the proceedings of the XVIII Latin American Algebra
Colloquium, held from August 3–8, 2009, in São Paulo, Brazil.

It includes research articles as well as up-to-date surveys
covering several directions of current research in algebra, such as
Asymptotic Codimension Growth, Hopf Algebras, Structure Theory of both
Associative and Non-Associative Algebras, Partial Actions of Groups on
Rings, and contributions to Coding Theory.

#### Readership

Graduate students and research mathematicians interested in group theory, associative and non-associative algebras, and coding theory.
