Bijection classes for type \(A_{2n}^{(2)}\).¶
Part of the (internal) classes which runs the bijection between rigged configurations and KR tableaux of type \(A_{2n}^{(2)}\).

TESTS:
sage: KRT = crystals.TensorProductOfKirillovReshetikhinTableaux(['A', 4, 2], [[2, 1]])
sage: from sage.combinat.rigged_configurations.bij_type_A2_even import KRTToRCBijectionTypeA2Even
sage: bijection = KRTToRCBijectionTypeA2Even(KRT(pathlist=[[-1,2]]))
sage: TestSuite(bijection).run()
sage: RC = RiggedConfigurations(['A', 4, 2], [[2, 1]])
sage: from sage.combinat.rigged_configurations.bij_type_A2_even import RCToKRTBijectionTypeA2Even
sage: bijection = RCToKRTBijectionTypeA2Even(RC(partition_list=[[],[]]))
sage: TestSuite(bijection).run()

class
sage.combinat.rigged_configurations.bij_type_A2_even.
KRTToRCBijectionTypeA2Even
(tp_krt)¶ Bases:
sage.combinat.rigged_configurations.bij_type_C.KRTToRCBijectionTypeC
Specific implementation of the bijection from KR tableaux to rigged configurations for type \(A_{2n}^{(2)}\).
This inherits from type \(C_n^{(1)}\) because we use the same methods in some places.
-
next_state
(val)¶ Build the next state for type \(A_{2n}^{(2)}\).
TESTS:
sage: KRT = crystals.TensorProductOfKirillovReshetikhinTableaux(['A', 4, 2], [[2,1]]) sage: from sage.combinat.rigged_configurations.bij_type_A2_even import KRTToRCBijectionTypeA2Even sage: bijection = KRTToRCBijectionTypeA2Even(KRT(pathlist=[[-1,-2]])) sage: bijection.cur_path.insert(0, []) sage: bijection.cur_dims.insert(0, [0, 1]) sage: bijection.cur_path[0].insert(0, [-2]) sage: bijection.next_state(-2)

RCToKRTBijectionTypeA2Even
(RC_element)¶ Bases:
sage.combinat.rigged_configurations.bij_type_C.RCToKRTBijectionTypeC
Specific implementation of the bijection from rigged configurations to tensor products of KR tableaux for type \(A_{2n}^{(2)}\).
