ABCT image as a positive geometry and genus-zero pair
Determine whether the image of the positive Grassmannian Gr(2,n)_{≥0} in the ABCT variety V(d+1,n) is a positive geometry, and establish whether V(d+1,n) with the relevant boundary forms a genus zero pair in the sense of Brown–Dupont.

The image of the positive Grassmannian ${\rm Gr}(2,n)_{\geq 0}$ in the ABCT variety $V(d+1,n)$ is a semialgebraic set. Is that image a positive geometry? Is $V(d+1,n)$ with the relevant boundary a genus zero pair, in the sense of ?
