Nikolaos Fountoulakis, Tejas Iyer
We introduce a model of evolving preferential attachment trees where vertices are assigned weights, and the evolution of a vertex depends not only on its own weight, but also on th…

Asymptotic enumeration of orientations of a graph as a function of the out-degree sequence
Mikhail Isaev, Tejas Iyer, Brendan D. McKay
We prove an asymptotic formula for the number of orientations with given out-degree (score) sequence for a graph . The graph is assumed to have average degrees at least $n^{…
