Algebraic singularities of scattering amplitudes from tropical geometry
Journal of High Energy Physics, 2021 We address the appearance of algebraic singularities in the symbol alphabet of scattering amplitudes in the context of planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory.

On Rational Equivalence in Tropical Geometry [PDF]
Canadian Journal of Mathematics, 2016 AbstractThis article discusses the concept of rational equivalence in tropical geometry (and replaces an older, imperfect version). We give the basic definitions in the context of tropical varieties without boundary points and prove some basic properties.

Estimates of tropical cyclone geometry parameters based on best-track data [PDF]
Natural Hazards and Earth System Sciences, 2019 Parametric wind profiles are commonly applied in a number of engineering applications for the generation of tropical cyclone (TC) wind and pressure fields.

A MODULI STACK OF TROPICAL CURVES
Forum of Mathematics, Sigma, 2020 We contribute to the foundations of tropical geometry with a view toward formulating tropical moduli problems, and with the moduli space of curves as our main example.

Tropical ideals do not realise all Bergman fans [PDF]
, 2021 Every tropical ideal in the sense of Maclagan–Rincón has an associated tropical variety, a finite polyhedral complex equipped with positive integral weights on its maximal cells.

Watershed controls and tropical cyclone-induced changes in river hydraulic geometry in Puerto Rico
Journal of Hydrology: Regional Studies, 2022 Study region: 24 stream gaging sites in Puerto Rico. Study focus: At-a-station hydraulic geometry (AHG), which describes how channel width, depth, and velocity vary with discharge at a river cross section, has long been used to study fluvial processes ...

Tropical Geometry and Mechanism Design
CoRR, 2016 We develop a novel framework to construct and analyze finite valued, multidimensional mechanisms using tropical convex geometry. We geometrically characterize incentive compatibility using cells in the tropical convex hull of the type set. These cells are the sets of incentive compatible payments and form tropical simplices, spanned by generating ...
