[图书][B] Introduction to tropical geometry

D Maclagan, B Sturmfels - 2015 - books.google.com
Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral
tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the …

[图书][B] Triangulations: structures for algorithms and applications

J De Loera, J Rambau, F Santos - 2010 - books.google.com
Triangulations presents the first comprehensive treatment of the theory of secondary
polytopes and related topics. The text discusses the geometric structure behind the …

[图书][B] Essentials of tropical combinatorics

M Joswig - 2021 - books.google.com
The goal of this book is to explain, at the graduate student level, connections between
tropical geometry and optimization. Building bridges between these two subject areas is …

Sharp bounds for the number of regions of maxout networks and vertices of minkowski sums

G Montúfar, Y Ren, L Zhang - SIAM Journal on Applied Algebra and Geometry, 2022 - SIAM
We present results on the number of linear regions of the functions that can be represented
by artificial feedforward neural networks with maxout units. A rank-maxout unit is a function …

The positive Dressian equals the positive tropical Grassmannian

D Speyer, L Williams - Transactions of the American Mathematical Society …, 2021 - ams.org
The Dressian and the tropical Grassmannian parameterize abstract and realizable tropical
linear spaces; but in general, the Dressian is much larger than the tropical Grassmannian …

Subdivisions and triangulations of polytopes

CW Lee, F Santos - Handbook of discrete and computational …, 2017 - taylorfrancis.com
We are interested in the set of all subdivisions or triangulations of a given polytope P and
with a fixed finite set V of points that can be used as vertices. V must contain the vertices of …

[HTML][HTML] Stiefel tropical linear spaces

A Fink, F Rincón - Journal of Combinatorial Theory, Series A, 2015 - Elsevier
The tropical Stiefel map associates to a tropical matrix A its tropical Plücker vector of
maximal minors, and thus a tropical linear space L (A). We call the L (A) s obtained in this …

Arboreal singularities

D Nadler - Geometry & Topology, 2017 - msp.org
We introduce a class of combinatorial singularities of Lagrangian skeleta of symplectic
manifolds. The link of each singularity is a finite regular cell complex homotopy equivalent to …

Geometry of 𝜈-Tamari lattices in types 𝐴 and 𝐵

C Ceballos, A Padrol, C Sarmiento - Transactions of the American …, 2019 - ams.org
In this paper, we exploit the combinatorics and geometry of triangulations of products of
simplices to derive new results in the context of Catalan combinatorics of $\nu $-Tamari …

Algebraic and geometric methods in enumerative combinatorics

F Ardila - Handbook of enumerative combinatorics, 2015 - api.taylorfrancis.com
Enumerative combinatorics is about counting. The typical question is to find the number of
objects with a given set of properties. However, enumerative combinatorics is not just about …
