*José A. de la Peña; Ernesto Vallejo; Natig Atakishiyev*

The Latin-American conference on algebra, the XV Coloquio Latinoamericano de
Álgebra (Cocoyoc, México), consisted of plenary sessions of general interest
and special sessions on algebraic combinatorics, associative rings, cohomology
of rings and algebras, commutative algebra, group representations, Hopf
algebras, number theory, quantum groups, and representation theory of algebras.

This proceedings volume contains original research papers related to talks at
the colloquium. In addition, there are several surveys presenting important
topics to a broad mathematical audience. There are also two invited papers by
Raymundo Bautista and Roberto Martínez, founders of the Mexican school of
representation theory of algebras.

The book is suitable for graduate students and researchers interested in
algebra.

#### Readership

Graduate students and research mathematicians interested in algebra.
