系统发生代数几何关注的是从有限树导出的某些复杂的投影代数簇。这些变种上的真实的正点代表了进化的概率模型。对于小树,我们恢复经典的几何对象,如复曲面和行列式的品种和割线品种,但较大的树木导致新的,在很大程度上是未开发的领域。本文给出了一个独立的介绍这一主题,并提供了许多开放的问题代数几何。
Phylogenetic algebraic geometry is concerned with certain complex projective algebraic varieties derived from finite trees. Real positive points on these varieties represent probabilistic models of evolution. For small trees, we recover classical geometric objects, such as toric and determinantal varieties and their secant varieties, but larger trees lead to new and largely unexplored territory. This paper gives a self-contained introduction to this subject and offers numerous open problems for algebraic geometers.
