Computing Embeddings and Isomorphisms of Finite Semigroups
James East, Attila Egri-Nagy, Andrew R. Francis +1
Semigroup theory is a branch of abstract algebra, and it provides mathematical tools for the theory of computation. Finite semigroups can describe state transition systems and thus…
Binary normal networks without near reticulations can be reconstructed from their rooted triples
Andrew Francis, Charles Semple
Normal networks are an important class of phylogenetic networks that have compelling mathematical properties which align with intuition about inference from genetic data. While too…
"Normal" phylogenetic networks may be emerging as the leading class
Andrew Francis
The rich and varied ways that genetic material can be passed between species has motivated extensive research into the theory of phylogenetic networks. Features that align with bio…
Counting spinal phylogenetic networks
Andrew Francis, Michael Hendriksen
Phylogenetic networks are an important way to represent evolutionary histories that involve reticulations such as hybridization or horizontal gene transfer, yet fundamental questio…
