Combinatorial Topological Models for Phylogenetic Networks and the Mergegram Invariant
PaweÅ DÅotko, Jan Felix Senge, Anastasios Stefanou
Mutations of genetic sequences are often accompanied by their recombinations, known as phylogenetic networks. These networks are typically reconstructed from coalescent processes t…
