Title: Restrictions of Projective Duals

Abstract: The determinant of a matrix factors when one restricts to even-sized skew-symmetric matrices, but remains irreducible for symmetric matrices. Why is this? I’ll explain this in the context of projective duality and its restriction. I’ll focus on several examples that served as inspiration for recent work with F. Holweck.
