在这里,我们介绍研究人员在代数生物学的令人兴奋的新领域cophylogenetics。同源遗传学是研究伴随进化的生物(或基因),如宿主和寄生虫物种。因此,同源发生学研究的自然对象是相关树的元组,而不是单个树。我们回顾了遗传学代数统计中的各种研究课题,并提出了同源遗传学的类似物。特别是,我们提出了空间的cophylogenetic树,cophylogenetic重建,和cophylogenetic不变量。最后,我们以开放的问题结束。
Here we introduce researchers in algebraic biology to the exciting new field of cophylogenetics. Cophylogenetics is the study of concomitantly evolving organisms (or genes), such as host and parasite species. Thus the natural objects of study in cophylogenetics are tuples of related trees, instead of individual trees. We review various research topics in algebraic statistics for phylogenetics, and propose analogs for cophylogenetics. In particular we propose spaces of cophylogenetic trees, cophylogenetic reconstruction, and cophylogenetic invariants. We conclude with open problems.
