Nearest Points on Toric Varieties
Martin Helmer, Bernd Sturmfels
We determine the Euclidean distance degree of a projective toric variety. This extends the formula of Matsui and Takeuchi for the degree of the -discriminant in terms of Euler o…

On the Euler characteristic of a relative hypersurface
James Fullwood, Martin Helmer
We derive a general formula for the Euler characteristic of a fibration of projective hypersurfaces in terms of invariants of an arbitrary base variety. When the general fiber is a…
