This volume contains the proceedings of the Conference on Representations of Algebras - Sao Paulo (CRASP), held at the Instituto de Matematica e Estatistica of the Universidade de Sao Paulo, Brazil. It discusses Hopf, tubular, quasischurian, wild hereditary, concealed-canonical Artin, Brauer star, and Koszul algebras.
"This is the proceedings of the CRASP conference at the University of Sao Paulo. It covers a wide range of topics in representation theory … . It is an excellent source on recent progress in the representation theory of Artin algebras and related areas of mathematics and physics. Researchers and graduate students will benefit from it."
