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.
Table of Contents
On the existence of left and right almost split morphisms; actions of Hopf algebras on quantum polynomials; strongly simply connected derived tubular algebras; H1 and presentations of finite dimensional algebras; tame tilted algebras with almost regular connecting components; reflexive modules are not closed under submodules; fibre sum functors and the bimodule ext; smooth automorphism group schemes; a combinatorial characterization of hereditary categories containing simple objects; symmetric quasi-Schurian algebras; on lattices at the ends of connected components of the Auslander-Reiten quiver; factorizations of morphisms for wild hereditary algebra; a note on concealed-canonical Artin algebras; Koszul algebras and the Gorenstein condition; some remarks about the double extension algebra of a finite poset; coil algebras that are derived-tame; one-point extensions of quasitilted algebras by modules on stable tubes; combinatorial partial tilting complexes for the Brauer star algebras; almost split sequences in categories of representations of quivers II; cotilting objects and dualities; coherent components of Auslander-Reiten quivers whose DTr-orbits are finite; twisted Hopf 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."
