Description (last modified by aschilling)

Implementation of affine crystals from classical crystals:

  • input is a classical crystal together with an automorphism
  • result is an affine crystal

Implementation of Kirillov Reshetikhin crystals:

  • Type A_n{(1)} KR crystals are implemented.
  • Type D_n{(1)}, B_n{(1)}, A_{2n}{(2)} KR crystals are implemented using plus-minus diagrams

Depends on trac ticket #4326 on root systems.
