Jaeger-type orientations of random regular graphs

Catherine Greenhill, Mikhail Isaev, Charles Lewis

We consider -orientations, which are defined to be orientations of -regular graphs such that every vertex either has in-degree or out-degree . These generalise the ori…

Canonical labelling of random regular graphs

Mikhail Isaev, Tamás Makai, Brendan McKay +3

We prove that whenever and as , then with high probability for any non-trivial initial colouring, the colour refinement algorithm disti…

On Pauling's residual entropy estimate for regular graphs with growing degree

M. Hasheminezhad, M. Isaev, B. D. McKay +1

In 1935, Pauling proposed an estimate for the number of Eulerian orientations of a graph in the context of the theoretical behaviour of water ice. The logarithm of the number of Eu…

Sandwiching between random regular graphs and Erdős-Rényi graphs: configuration model and unions of perfect matchings

Pu Gao, Mikhail Isaev, Xavier Perez-Gimenez

We establish new couplings among several random graph and multigraph models related to the random regular graph , including the configuration model and unions of random per…

A tail bound for cumulant series for complex functions of independent random variables

Mikhail Isaev

We obtain explicit bounds on the truncation error of the cumulant series of a bounded complex function of a random vector with independent components. The bounds are based on multi…

Asymptotic enumeration of graph factors by cumulant expansion

Mikhail Isaev, Brendan D. McKay

Let be a dense graph with good expansion properties and not too close to being bipartite. Let be a graphical degree sequence. Under very weak conditions, we fin…
