The Schur superpolynomial identification conjecture

A superpartition is denoted by $[?]$; let $s^c_\Lambda(x,\theta)$ be the combinatorially defined Schur superpolynomial and let $s_\Lambda(x,\theta)$ be the specialization at $q=t=0$ of the Macdonald superpolynomial. Their Kostka coefficients are denoted by $\bar{K}^c_{\Lambda\Omega}$ and $\bar{K}_{\Lambda\Omega}$, respectively. Schur superpolynomial identification conjecture.

$$s^c_\Lambda(x,\theta)=s_\Lambda(x,\theta),$$

equivalently,

$$\bar{K}^c_{\Lambda\Omega}=\bar{K}_{\Lambda\Omega}.$$

This conjecture identifies the combinatorial construction with the Macdonald-superpolynomial specialization and supplies the intended link between the two descriptions; the source gives no resolution status.
