R-Modules


Changes:

  • The function RSpaceWithBasis now works over general euclidean rings (not just fields).
  • New function IsPermutationModule for A-modules.
  • New function CentreOfEndomorphismRing for A-modules, which computes the centre of the endomorphism ring of a module (and is generally much faster than computing the endomorphism ring and then its centre for some rings).
