Weba matroid, to explore its connections to complex algebraic geometry (in particular to Hodge theory), and to give an overview of the Hodge theory of matroids developed in [AHK18] and its application to the log-concavity conjecture. A good and concise survey of the topics covered in this seminar is [Bak18], which can be WebBuilding on a recent paper [8], here we argue that the combinatorics of matroids are intimately related to the geometry and topology of toric hyperkähler varieties. We show that just like toric varieties occupy a central role in Stanley’s proof for the necessity of McMullen’s conjecture (or g -inequalities) about the classification of face ...

The geometry of geometries: matroid theory, old and new
WebAug 2, 2012 · Matroid theory is a vibrant area of research that provides a unified way to understand graph theory, linear algebra and combinatorics via finite geometry. This book provides the first comprehensive introduction to the field which will appeal to undergraduate students and to any mathematician interested in the geometric approach to matroids. WebFor example, matroids arise as graphs in discrete mathematics and as diminishing-return functions in optimization. In particular, the interpretation of matroids as hyperplane … WebJan 1, 1996 · Abstract and Figures. We present an array of matroids drawn from three sources in discrete applied geometry: (i) static (or first-order) rigidity of frameworks and higher skeletal rigidity; (ii ... business without investment online
