Abstract: Phylogenetic trees, which is inferring evolutionary histories, has important applications in biology, criminology and public health. This talk presents a continuous space which models the set of all phylogenetic trees having a fixed set of leaves. This space has a natural metric of non-positive curvature, allowing a valid procedure for averaging or combining several trees whose leaves are identical. This talk also presents limiting behavior of such averaged trees. Relevant paper.
