Journal ArticleDOI
The Euclidean Distance Degree of an Algebraic Variety
TL;DR: A theory of such nearest point maps of a real algebraic variety with respect to Euclidean distance from the perspective of computational algebraic geometry is developed.
Journal ArticleDOI
A tropical proof of the Brill-Noether Theorem
TL;DR: In this article, the Brill-Noether Theorem was shown to hold for general graphs in every genus, confirming a conjecture of Baker and giving a new proof of the Brill Theorem over any algebraically closed field.
Journal ArticleDOI
A tropical approach to secant dimensions
TL;DR: Tropical geometry yields good lower bounds, in terms of certain combinatorial polyhedral optimisation problems, on the dimensions of secant varieties as discussed by the authors, especially for toric varieties such as Segre-Veronese embeddings.
Journal ArticleDOI
Trek separation for Gaussian graphical models
TL;DR: This work gives a precise graph-theoretic characterization of when submatrices of the covariance matrix have small rank for a general class of mixed graphs that includes directed acyclic and undirected graphs as special cases.
