Tropical spectrahedra
We introduce tropical spectrahedra, defined as the images by the nonarchimedean
valuation of spectrahedra over the field of real Puiseux series. We provide an explicit …

Factorization of polynomials over the symmetrized tropical semiring and Descartes' rule of sign over ordered valued fields
M Akian, S Gaubert, H Tavakolipour - arXiv preprint arXiv:2301.05483, 2023 - arxiv.org
The symmetrized tropical semiring is an extension of the tropical semifield, initially
introduced to solve tropical linear systems using Cramer's rule. It is equivalent to the real …

Hahn analytification and connectivity of higher rank tropical varieties
T Foster, D Ranganathan - manuscripta mathematica, 2016 - Springer
We show that the tropicalization of a connected variety over a higher rank valued field is a
path connected topological space. This establishes an affirmative answer to a question …

Local tropicalization
P Popescu-Pampu, D Stepanov - arXiv preprint arXiv:1204.6154, 2012 - arxiv.org
In this paper we propose a general functorial definition of the operation of\emph {local
tropicalization} in commutative algebra. Let $ R $ be a commutative ring, $\Gamma $ a …

Convergent Hahn series and tropical geometry of higher rank
M Joswig, B Smith - Journal of the London Mathematical …, 2023 - Wiley Online Library
We propose to study the tropical geometry specifically arising from convergent Hahn series
