Bijection classes for type \(D_n^{(1)}\)#

Part of the (internal) classes which runs the bijection between rigged configurations and KR tableaux of type \(D_n^{(1)}\).

class sage.combinat.rigged_configurations.bij_type_D.KRTToRCBijectionTypeD(tp_krt)#

Bases: KRTToRCBijectionTypeA

Specific implementation of the bijection from KR tableaux to rigged configurations for type \(D_n^{(1)}\).

This inherits from type \(A_n^{(1)}\) because we use the same methods in some places.

doubling_map()#

Perform the doubling map of the rigged configuration at the current state of the bijection.

This is the map \(B(\Lambda) \hookrightarrow B(2 \Lambda)\) which doubles each of the rigged partitions and updates the vacancy numbers accordingly.

halving_map()#

Perform the halving map of the rigged configuration at the current state of the bijection.

This is the inverse map to \(B(\Lambda) \hookrightarrow B(2 \Lambda)\) which halves each of the rigged partitions and updates the vacancy numbers accordingly.

next_state(val)#: Build the next state for type \(D_n^{(1)}\).

run(verbose=False)#

Run the bijection from a tensor product of KR tableaux to a rigged configuration for type \(D_n^{(1)}\).

INPUT:

tp_krt – A tensor product of KR tableaux
verbose – (Default: False) Display each step in the bijection

EXAMPLES:

sage: KRT = crystals.TensorProductOfKirillovReshetikhinTableaux(['D', 4, 1], [[2,1]])
sage: from sage.combinat.rigged_configurations.bij_type_D import KRTToRCBijectionTypeD
sage: KRTToRCBijectionTypeD(KRT(pathlist=[[-3,2]])).run()
