Anomalous heat-kernel decay for random walk among bounded random conductances [PDF]
We consider the nearest-neighbor simple random walk on $\Z^d$, $d\ge2$, driven by a field of bounded random conductances $\omega_{xy}\in[0,1]$. The conductance law is i.i.d.

Moments of partition functions of 2D Gaussian polymers in the weak disorder regime – II [PDF]
Let $W_N(\beta) = \mathrm{E}_0\left[e^{ \sum_{n=1}^N \beta \omega(n,S_n) - N\beta^2/2}\right]$ be the partition function of a two-dimensional directed polymer in a random environment, where $\omega(i,x), i\in \mathbb{N}, x\in \mathbb{Z}^2$ are i.i.d ...

Ramification of Volterra-type rough paths [PDF]
We extend the new approach introduced in arXiv:1912.02064v2 [math.PR] and arXiv:2102.10119v1 [math.PR] for dealing with stochastic Volterra equations using the ideas of Rough Path theory and prove global existence and uniqueness results. The main idea of

Estimating the probability that a given vector is in the convex hull of a random sample [PDF]
For a d -dimensional random vector X , let $$p_{n, X}(\theta )$$ p n , X ( θ ) be the probability that the convex hull of n independent copies of X contains a given point $$\theta $$ θ . We provide several sharp inequalities regarding $$p_{n, X}(\theta )$

Dissipative probability vector fields and generation of evolution semigroups in Wasserstein spaces [PDF]
We introduce and investigate a notion of multivalued $$\lambda $$ λ -dissipative probability vector field (MPVF) in the Wasserstein space $$\mathcal {P}_2({\textsf {X} })$$ P 2 ( X ) of Borel probability measures on a Hilbert space $${\textsf {X} }$$ X .

Support and density of the limit $m$-ary search trees distribution [PDF]
The space requirements of an $m$-ary search tree satisfies a well-known phase transition: when $m\leq 26$, the second order asymptotics is Gaussian. When $m\geq 27$, it is not Gaussian any longer and a limit $W$ of a complex-valued martingale arises.

Asymptotic behavior of some statistics in Ewens random permutations [PDF]
The purpose of this article is to present a general method to find limiting laws for some renormalized statistics on random permutations. The model considered here is Ewens sampling model, which generalizes uniform random permutations.

The expected number of inversions after n adjacent transpositions [PDF]
We give a new expression for the expected number of inversions in the product of n random adjacent transpositions in the symmetric group S_{m+1}. We then derive from this expression the asymptotic behaviour of this number when n scales with m in various ...

Mean field analysis for inhomogeneous bike sharing systems [PDF]
In the paper, bike sharing systems with stations having a finite capacity are studied as stochastic networks. The inhomogeneity is modeled by clusters.
