Abstract: How does projective duality between points and lines on the plane behave in families and under degenerations?
I will compare an approach to degenerations and moduli of lines (Keel-Tevelev) and points (Gerritzen-Piwek) on the plane.
Tropical planes and especially their incarnation as skeletons (membranes) in the Bruhat-Tits building will play an important role.
This is joint work with Luca Schaffler.
