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 plus-minus diagrams 13 - Type D_n^{(1)}, B_n^{(1)}, A_{2n-1}^{(2)} KR crystals are implemented using plus-minus 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.
