Ticket #3663 – Description
v3 v4 1 1 Implementation of affine crystals from classical crystals: 2  input is a classical crystal together with an automorphism 3  result is an affine crystal 2  input is a classical crystal 3  an affine crystal can be constructed by providing the methods e0 and f0 4 5 Implementation of affine crystals from classical crystal and promotion: 6  input is a classical crystal and a promotion operators which corresponds 7 to a Dynkin diagram automorphism 8  the methods e0 and f0 are computed using the promotion operator 4 9 5 10 Implementation of Kirillov Reshetikhin crystals: 6 11 7 12  Type A_n^{(1)} KR crystals are implemented. 8  Type D_n^{(1)}, B_n^{(1)}, A_{2n}^{(2)} KR crystals are implemented using plusminus diagrams 13  Type D_n^{(1)}, B_n^{(1)}, A_{2n1}^{(2)} KR crystals are implemented using plusminus diagrams 14 to construct the promotion operator which corresponds to interchanging nodes 0 and 1 15  Type C_n^{(1)} KR crystals are implemented; the methods e0 and f0 are constructed 16 using an embedding into the ambient crystal of type A_{2n+1}^{(2)} 9 17 10 18 Depends on trac ticket #4326 on root systems.
