Packages

crep 1.2 Version 1.2 of the basic (or main) package of the CREP system, including LaTeX sources for volumes 1 & 2 of the CREP manual.
(Dealing mainly with unit forms, posets and bound poset algebras.)
crep 1.3 Version 1.3 of the basic (or main) package of the CREP system, including LaTeX sources for volumes 1 - 3 of the CREP manual.
esrd Data base on exceptional sincere representation-directed algebras.
get_alg An interface for interactive input and display of quivers and relations.
hall_e8 The hall_e8 package on Hall polynomials for an algebra of type E8
heralg Version 1.2 of the heralg package for hereditary algebras.
nor Counting representations over small quivers.
repetit Data base and functions for repetitive and iteratedly tilted algebras.
tpe Data base on tame poset algebras arising from algebras of type E6~, E7~ or E8~.
tubular The tubular package for canonical algebras and weighted projective lines.
uforms The uforms package for unit forms.
ufstrong The ufstrong package for "strong" properties of unit forms.
xpre A family of functions for the computation of preprojective components of the Auslander Reiten quiver of an algebra. (Together with their own graphical interface.)
