From Hurwitz numbers to Feynman diagrams: Counting rooted trees in log gravity
We show that the partition function of the logarithmic sector of critical topologically massive gravity which represents a series expansion of composition of functions, can be expressed as a sum over rooted trees. Our work brings a connection between integrable hierarchies of mathematical physics, c...
