Introduction to the heralg package

CALLING SEQUENCE:
<function>(args)
heralg[<function>](args)

SYNOPSIS:

The heralg package is a collection of routines for calculations with quiver algebras.

To use a heralg function, either define that function alone using the command with(heralg, <function>), or define all heralg functions using the command with(heralg). Alternatively, invoke the function using the long form heralg[<function>].

The functions available are:

cartan_matrix
cartan_inverse
coxeter_matrix
coxeter_inverse
coxeter_polynomial
coxeter_roots growth_number
homol_blf
one_pt_cartmatrix
one_pt_coxmatrix
one_pt_coxpoly tau_translate
perpgen
perp_quiver
perp_cm
star

For more information on a particular function see heralg[<function>].

The heralg package uses the type heralg/quiverdata to describe quivers.
