Linear Independence for ⁽¹⁾₁ by Using ⁽¹⁾₂

In the previous paper, the authors proved linear independence of the combinatorial spanning set for the standard ⁽¹⁾ℓ-module (Λ₀) by establishing a connection with the combinatorial basis of Feigin-Stoyanovsky's type subspace (Λ₀) of ⁽¹⁾2ℓ-module (Λ₀). In this note, we extend this argument for...

Description
Summary:In the previous paper, the authors proved linear independence of the combinatorial spanning set for the standard ⁽¹⁾ℓ-module (Λ₀) by establishing a connection with the combinatorial basis of Feigin-Stoyanovsky's type subspace (Λ₀) of ⁽¹⁾2ℓ-module (Λ₀). In this note, we extend this argument for ⁽¹⁾₁ ≅ ⁽¹⁾₁ to all standard ⁽¹⁾₁-modules (Λ). In the proof, we use a coefficient of an intertwining operator of the type ((Λ₂)(Λ₁) (Λ₁)) for standard ⁽¹⁾₂-modules.
