  • Ticket #3663 – Description

    v3 v4  
    11Implementation 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
     5Implementation 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
    49
    510Implementation of Kirillov Reshetikhin crystals:
    611
    712- 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)}
