Small ball probabilities for linear images of high dimensional distributions [PDF]
We study concentration properties of random vectors of the form $AX$, where $X = (X_1, ..., X_n)$ has independent coordinates and $A$ is a given matrix. We show that the distribution of $AX$ is well spread in space whenever the distributions of $X_i$ are

Asymptotics of Karhunen–Loève Eigenvalues for Sub-Fractional Brownian Motion and Its Application
In the present paper, the Karhunen–Loève eigenvalues for a sub-fractional Brownian motion are considered. Rigorous large n asymptotics for those eigenvalues are shown, based on the functional analysis method.

Quantitative invertibility of random matrices: a combinatorial perspective
Quantitative invertibility of random matrices: a combinatorial perspective, Discrete Analysis 2021:10, 38 pp. This paper concerns the general and much studied question of how likely a large random real or complex square matrix is to be invertible, and ...

Small ball probabilities for stable convolutions [PDF]
Summary: We investigate the small deviations under various norms for stable processes defined by the convolution of a smooth function \(f : \; ]0, +\infty[ \;\to \mathbb{R} \) with a real \(S\alpha S\) Lévy process. We show that the small ball exponent is uniquely determined by the norm and by the behaviour of \(f\) at zero, which extends the results ...

Small Ball Probability, Inverse Theorems, and Applications [PDF]
Let $ $ be a real random variable with mean zero and variance one and $A={a_1,...,a_n}$ be a multi-set in $\R^d$. The random sum $$S_A := a_1 _1 + ... + a_n _n $$ where $ _i$ are iid copies of $ $ is of fundamental importance in probability and its applications.

Small ball probability and Dvoretzky’s Theorem
Large deviation estimates are by now a standard tool inthe Asymptotic Convex Geometry, contrary to small deviationresults. In this note we present a novel application of a smalldeviations inequality to a problem related to the diameters of random sections of high dimensional convex bodies.

Hitting spheres on hyperbolic spaces [PDF]
For a hyperbolic Brownian motion on the Poincar\'e half-plane $\mathbb{H}^2$, starting from a point of hyperbolic coordinates $z=(\eta, \alpha)$ inside a hyperbolic disc $U$ of radius $\bar{\eta}$, we obtain the probability of hitting the boundary ...

Low Diameter Graph Decompositions by Approximate Distance Computation [PDF]
In many models for large-scale computation, decomposition of the problem is key to efficient algorithms. For distance-related graph problems, it is often crucial that such a decomposition results in clusters of small diameter, while the probability that ...
