Positive Geometry of Yang-Mills Correlators
Mattia Arundine, Veronica Calvo Cortes, Joris Koefler +1
We develop a positive-geometric formulation of tree-level Yang-Mills correlators in de Sitter space at three and four points through their helicity-stripped representatives on the…
Benchmarks in Leipzig
Andrei Balakin, Miklós Bóna, Marie-Charlotte Brandenburg +45
Between April 1 and May 15, 2026, a group of 49 mathematicians compiled a dataset of research-level mathematics questions with known answers. Most of the work was done during the t…
Dyck Paths, Configuration Spaces and Polytopes For Linear Nakayama algebras
Veronica Calvo Cortes, Hadleigh Frost
We present a combinatorial model of configuration spaces and polytopes associated to the quotients of , the path algebra of the linearly oriented quiver, i.e.…
Positive Charts of Toric Varieties
Veronica Calvo Cortes, Simon Telen
We construct affine charts of a smooth projective toric variety which contain its nonnegative points, and which admit a closed embedding into the total coordinate space of Cox's qu…
