Hierarchical pinning model: low disorder relevance in the $b=s$ case [PDF]

open access: yes, 2014
We consider a hierarchical pinning model introduced by B.Derrida, V.Hakim and J.Vannimenus which undergoes a localization/delocalization phase transition. This model depends on two parameters $b$ and $s$.

Bootstrap confidence sets for spectral projectors of sample covariance

open access: yes, 2017
Let $X_{1},\ldots,X_{n}$ be i.i.d. sample in $\mathbb{R}^{p}$ with zero mean and the covariance matrix $\mathbf{\Sigma}$. The problem of recovering the projector onto an eigenspace of $\mathbf{\Sigma}$ from these observations naturally arises in many ...

On a link between a species survival time in an evolution model and the Bessel distributions

open access: yes, 2011
We consider a stochastic model for species evolution. A new species is born at rate lambda and a species dies at rate mu. A random number, sampled from a given distribution F, is associated with each new species at the time of birth.
