In recent years, as one of the most prominent subclass among the many different classes of phylogenetic networks, the class of tree-child networks has attracted the attention of many mathematicians and biologists. However, until a few years ago, both exact and asymptotic counting for tree-child networks was still difficult, not to mention other problems. In this thesis, we will review the most important previous results for tree-child networks and their variants and add several new results.Our main contributions, which are mainly proved with tools from Combinatorics and Probability Theory, are as follows. For a recent conjecture on the exact counting of tree-childnetworks, we give a proof for the special case when the tree-child network is a one-component network. In addition, we prove the first stochastic results for tree-child networks which are picked uniformly at random. Also, we can extend the definition of tree-child networks and generalize previous and our results to the new class. Moreover, we have taken the previous research on limit laws of patterns in ranked tree-child network a step further and provided thefirst general patterns study for a class of phylogenetic networks.A short outline of the thesis is as follows: in Chapter 1, we give definitions and show some basic properties for tree-child networks, their extensions and ranked tree-child networks. Then, in Chapter 2, we introduce our tools. In Chapter 3 and Chapter 4, we focus on results for tree-child networks and their extensions, respectively. Next in Chapter 5, we generalize the former study on patterns of ranked tree-child networkto all patterns of height 1 and 2 and make a conjecture for patterns of any height. Finally, we finish the thesis in Chapter 6 with a conclusion.參考文獻 [1] F. Bienvenu, A. Lambert, M. Steel (2022). Combinatorial and stochastic properties of ranked tree-child networks, Random Struct.
