| Abstract: | Let A be a domestic canonical algebra over a finite field k.All indecomposable A-modules, which can be generated by A-modules with smaller dimension vector inside the Hall algebra H(A) of A,are classified;then systems of minimal homogeneous generators of H(A) are explicitly written out.Moreover,give an inductive algorithm for the representation of an indecomposable exceptional module as a R-linear combination of Hall multipication of any system of minimal generators. |
