基于子图统计量的多面体

Polytopes from Subgraph Statistics

Alexander Engström, Patrik Norén

摘要:

子图统计中的多面体具有重要的应用价值,极值图论中的一些定理和定理可以作为它的性质。我们已经研究了他们,以期对应用程序的刻大型显式多面体和半代数集时的刻面描述是棘手的。利用图的极限,引入并研究了称为曲圈的半代数集。从体积计算和代数描述中,我们发现了几个有趣的结构。

英文摘要:

Polytopes from subgraph statistics are important in applications and conjectures and theorems in extremal graph theory can be stated as properties of them. We have studied them with a view towards applications by inscribing large explicit polytopes and semi-algebraic sets when the facet descriptions are intractable. The semi-algebraic sets called curvy zonotopes are introduced and studied using graph limits. From both volume calculations and algebraic descriptions we find several interesting conjectures.
