Genus 0 characteristic numbers of the tropical projective plane
, 2013 Finding the so-called characteristic numbers of the complex projective plane ${\mathbb C}P^2$ is a classical problem of enumerative geometry posed by Zeuthen more than a century ago. For a given $d$ and $g$ one has to find the number of degree $d$ genus $

Product-Mix Auctions and Tropical Geometry [PDF]
Mathematics of Operations Research, 2019 In a recent and ongoing work, Baldwin and Klemperer explore a connection between tropical geometry and economics. They give a sufficient condition for the existence of competitive equilibrium in product-mix auctions of indivisible goods. This result, which we call the unimodularity theorem, can also be traced back to the work of Danilov, Koshevoy, and

Advanced Intelligent Discovery, EarlyView.This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Tropicalizing binary geometries
Le MatematicheThe type A cluster configuration space, commonly known as $\mathcal M_{0,n}$, is the very affine part of the binary geometry associated with the associahedron. The tropicalization of $\mathcal M_{0,n}$ can be realized as the space of phylogenetic trees and its signed tropicalizations as the dual-associahedron subfans. We give a concise overview of this

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Corrosion of metallic process equipment in chemical, marine, and offshore industries leads to significant maintenance costs and safety concerns. Conventional epoxy coatings, though widely applied, often deteriorate under harsh conditions due to microcracking, moisture ingress and lack of self‐healing capability.

Experimental methods for wind tunnel studies of seed dispersal by wind
Applications in Plant Sciences, EarlyView.Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

A fractal modification of the tropical algebra for noise removal and optimal control
Journal of Low Frequency Noise, Vibration and Active ControlThis paper proposes a fractal modification of tropical algebra for noise removal and optimal control. Fractal addition, fractal multiplication, and fractal dot product are defined and explained in a fractal space.
