The fermionic-degree-one Macdonald superpolynomial conjugation conjecture

Let Λ\Lambda be a superpartition of fermionic degree m=1m=1, let HΛH_\Lambda be the modified Macdonald superpolynomial, and let ψ\psi be the linear map defined on Schur superpolynomials by ψ(sΩ)=sΩ\psi(s_\Omega)=s_{\Omega^{\circledast}}. Conjugation conjecture. One has

ψ(HΛ)=HΛ.\psi(H_\Lambda)=H_{\Lambda^{\circledast}}.

This conjecture predicts that the map induced by the circledast operation intertwines the corresponding modified Macdonald superpolynomials in fermionic degree one. The text presents it as a conjectural non-stable-sector statement, with stable-sector cases proved in the paper.
