调和代数曲线与不相交剖分

Harmonic algebraic curves and noncrossing partitions

Jeremy Martin, David Savitt, Ted Singer

摘要:

受Gauss关于代数基本定理的第一个证明的启发,我们研究了调和代数曲线的拓扑。根据最大值原理,调和曲线没有有界分量,其拓扑由非交叉匹配的组合数据决定。类似地,每一个复多项式都会产生一个相关的组合对象,我们称之为篮球,它由一对满足一个附加约束的非交叉匹配组成。我们证明了每一个非交叉匹配产生的一些调和曲线,并由此推断,每一个篮球产生的一些多项式。

英文摘要:

Motivated by Gauss's first proof of the Fundamental Theorem of Algebra, we study the topology of harmonic algebraic curves. By the maximum principle, a harmonic curve has no bounded components; its topology is determined by the combinatorial data of a noncrossing matching. Similarly, every complex polynomial gives rise to a related combinatorial object that we call a basketball, consisting of a pair of noncrossing matchings satisfying one additional constraint. We prove that every noncrossing matching arises from some harmonic curve, and deduce from this that every basketball arises from some polynomial.
