Let $X \subset \mathbb{R}^k$ be a semi-algebraic set defined by a closed formula of complexity bounded by $C$, and let $\dim X=n$. A nested semi-algebraic filtration is a sequence…

Surjectivity conjecture. The map is surjective when $D$ and $D+v$ range over all effective odd theta characteristic divisors. The conjecture would ensure that the conditional step…

Let $A_1,A_2,\ldots,A_n$ be general projective cameras, and let $X_n\subseteq\mathbb{R}^{2n}$ be the affine multiview variety obtained by dehomogenizing the multiview variety assoc…
