The generalized Macdonald superpolynomial conjugation conjecture

Let Λ\Lambda and Λ\boxcircle\Lambda^{\boxcircle} be superpartitions such that Λ\boxcircle\Lambda^{\boxcircle} is obtained from Λ\Lambda by replacing a circle by a box. Let #(Λ,Λ\boxcircle)\#(\Lambda,\Lambda^{\boxcircle}) be the number of circles lying above the row in which that replacement occurs. Define the normalized modified Macdonald superpolynomial by

H^Λ=vΛHΛ,\widehat H_\Lambda=v_\Lambda H_\Lambda,

where

vΛ=sΛ/BΛ(1qaΛ(s)tlΛ(s)+1).v_\Lambda=\prod_{s\in\Lambda/\mathcal B\Lambda}\left(1-q^{a_{\Lambda^{\circledast}}(s)}t^{l_{\Lambda^*}(s)+1}\right).

Let ψ\psi be the linear map given by

ψ(sΛ)=ΩΩ=Λ\boxcircle(1)#(Λ,Ω)sΩ.\psi(s_\Lambda)=\sum_{\Omega\,|\,\Omega=\Lambda^{\boxcircle}}(-1)^{\#(\Lambda,\Omega)}s_\Omega.

Generalized conjugation conjecture. Then

ψ(H^Λ)=ΩΩ=Λ\boxcircle(1)#(Λ,Ω)H^Ω.\psi(\widehat H_\Lambda)=\sum_{\Omega\,|\,\Omega=\Lambda^{\boxcircle}}(-1)^{\#(\Lambda,\Omega)}\widehat H_\Omega.

The claim generalizes the fermionic-degree-one relation to arbitrary fermionic degree, where the resulting superpartition is not unique. The supplied text gives no resolution status.
