Multidimensional Tauberian theorems for vector-valued distributions [PDF]

open access: yes, 2014
We prove several Tauberian theorems for regularizing transforms of vector-valued distributions. The regularizing transform of f is given by the integral transform M-phi(f)(x, y) = (f * phi(y))(x), (x, y) is an element of R-n x R+, with kernel phi(y) (t) =

Convergence Rates of Subseries

open access: yes, 2018
Let $(x_n)$ be a positive real sequence decreasing to $0$ such that the series $\sum_n x_n$ is divergent and $\liminf_{n} x_{n+1}/x_n>1/2$. We show that there exists a constant $\theta \in (0,1)$ such that, for each $\ell>0$, there is a subsequence $(x_ ...

No zero-crossings for random polynomials and the heat equation [PDF]

open access: yes, 2015
Consider random polynomial $\sum_{i=0}^na_ix^i$ of independent mean-zero normal coefficients $a_i$, whose variance is a regularly varying function (in $i$) of order $\alpha$. We derive general criteria for continuity of persistence exponents for centered

Approximation by proper holomorphic maps and tropical power series

open access: yes, 2017
Let $w$ be an unbounded radial weight on the complex plane. We study the following approximation problem: find a proper holomorphic map $f: \mathbb{C}\to\mathbb{C}^n$ such that $|f|$ is equivalent to $w$.

Optimality of embeddings of Bessel-potential-type spaces into generalized Hölder spaces [PDF]

open access: yes, 2005
We establish the sharpness of embedding theorems for Bessel-potential spaces modelled upon Lorentz-Karamata spaces and we prove the non compactness of such embeddings. Target spaces in our embeddings are generalized Hölder spaces.

Approximation of high quantiles from intermediate quantiles

open access: yes, 2016
Motivated by applications requiring quantile estimates for very small probabilities of exceedance, this article addresses estimation of high quantiles for probabilities bounded by powers of sample size with exponents below -1.

Book inequalities

open access: yes, 2014
Information theoretical inequalities have strong ties with polymatroids and their representability. A polymatroid is entropic if its rank function is given by the Shannon entropy of the subsets of some discrete random variables.

Indices of O-regular variation for weight functions and weight sequences

open access: yes, 2018
A plethora of spaces in Functional Analysis (Braun-Meise-Taylor and Carleman ultradifferentiable and ultraholomorphic classes; Orlicz, Besov, Lipschitz, Lebesque spaces, to cite the main ones) are defined by means of a weighted structure, obtained from a
