Consider a family of random ordered graph trees (T n ) n≥1 , where T n has n vertices. It has previously been established that if the associated search-depth processes converge to the normalised ...

In a new study published in Mathematical Biology, Popovic and recent Concordia graduate Mariolys Rivas (PhD 14) show how the present-day distribution of physical traits across species can help explain ...

The Yule tree graph The Yule tree is a graph with one edge coming in and two edges coming out of each branch-point. The branches represent the time periods between the evolution of new species. If the ...
