Description (last modified by )
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.
