Random permutations with logarithmic cycle weights
@article{Robles2018RandomPW, title={Random permutations with logarithmic cycle weights}, author={Nicolas Robles and Dirk Zeindler}, journal={arXiv: Probability}, year={2018} }
We consider random permutations on $\Sn$ with logarithmic growing cycles weights and study the asymptotic behavior as the length $n$ tends to infinity. We show that the cycle count process converges to a vector of independent Poisson variables and also compute the total variation distance between both processes. Next, we prove a central limit theorem for the total number of cycles. Furthermore we establish a shape theorem and a functional central limit theorem for the Young diagrams associated…
