Peakword Condensation and Submodule Lattices: An Application of the Meat-Axe

  title={Peakword Condensation and Submodule Lattices: An Application of the Meat-Axe},
  author={Klaus Lux and J{\"u}rgen M{\"u}ller and Michael Ringe},
  journal={J. Symb. Comput.},
We describe a new condensation method for computing the submodule lattice of a module for a finite dimensional algebra over a finite field, which exploits the idea of condensation and extends it to the case of primitive idempotents. The method has been implemented in the new C version of the Meat-Axe developed at Aachen, and we give several examples which have been analysed with our method.
