Pseudographs

Pseudograph induced bases

Warning

The basis PseudographDeformBasis can currently only be used for exterior and symmetric powers of the standard module of special orthogonal Lie algebras.

PBWDeformations.PseudographDeformBasis — Type

Concrete subtype of DeformBasis. Each element of the basis is induced by a pseudograph with two vertices and certain properties, which gets transformed to an arc diagram and then handled as in ArcDiagDeformBasis. This process is due to [FM22].

Given a basis element of an above basis, one can lookup all pseudographs that induce it (up to a scalar). See lookup_data for more details.
