Enumerative aspects of the Gross-Siebert program [PDF]

open access: yes, 2014
We present enumerative aspects of the Gross-Siebert program in this introductory survey. After sketching the program's main themes and goals, we review the basic definitions and results of logarithmic and tropical geometry.

Watershed controls and tropical cyclone-induced changes in river hydraulic geometry in Puerto Rico

open access: yesJournal 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 ...

Geometric Monodromy around the Tropical Limit [PDF]

open access: yes, 2016
Let $\{V_q\}_{q}$ be a complex one-parameter family of smooth hypersurfaces in a toric variety. In this paper, we give a concrete description of the monodromy transformation of $\{V_q\}_q$ around $q=\infty$ in terms of tropical geometry. The main tool is

Tropical geometry over the tropical hyperfield

open access: yesRocky Mountain Journal of Mathematics, 2022
In this text, we merge ideas around the tropical hyperfield with the theory of ordered blueprints to give a new formulation of tropical scheme theory. The key insight is that a nonarchimedean absolute value can be considered as a morphism into the tropical hyperfield.

A new tropical cyclone surge index incorporating the effects of coastal geometry, bathymetry and storm information

open access: yesScientific Reports, 2021
This study presents a new storm surge hazard potential index (SSHPI) for estimating tropical cyclone (TC) induced peak surge levels at a coast. The SSHPI incorporates parameters that are often readily available at real-time: intensity in 10-min maximum ...

Generating reliable estimates of tropical-cyclone-induced coastal hazards along the Bay of Bengal for current and future climates using synthetic tracks [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2022
Deriving reliable estimates of design water levels and wave conditions resulting from tropical cyclones is a challenging problem of high relevance for, among other things, coastal and offshore engineering projects and risk assessment studies.

On the Interaction between the Depth and Elevation of External Shading Devices in Tropical Daylit Classrooms with Symmetrical Bilateral Openings

open access: yesBuildings, 2022
External shading devices are an important design feature in tropical buildings, particularly for climate mitigation. However, the interaction between the depth and elevation of the shading devices and their impact on indoor daylight performance is not ...

Singularities of eight- and nine-particle amplitudes from cluster algebras and tropical geometry

open access: yesJournal of High Energy Physics, 2021
We further exploit the relation between tropical Grassmannians and Gr(4, n) cluster algebras in order to make and refine predictions for the singularities of scattering amplitudes in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory at higher ...

Tropical Geometry and the Motivic Nearby Fiber [PDF]

open access: yes, 2011
We construct motivic invariants of a subvariety of an algebraic torus from its tropicalization and initial degenerations. More specifically, we introduce an invariant of a compactification of such a variety called the "tropical motivic nearby fiber ...

Geometric Representations of Interacting Maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2010
Tropical geometry is a kind of dynamical scale transform which connects automata with real rational dynamics. Real rational dynamics are deeply studied from global analytic viewpoints.
