This paper is a survey paper on old and recent results on direction problems in finite dimensional affine spaces over a finite field.

These informal notes deal with Fourier series in one or more variables, Fourier transforms in one variable, and related matters.

We survey some results on toric topology.

This is a survey of results on random group presentations, and on random subgroups of certain fixed groups. Being a survey, this paper does not contain new results, but it offers a synthetic view of a part of this very active field of…

This article is an expository paper. We first survey developments over the past three decades in the theory of harmonic analysis on reductive symmetric spaces. Next we deal with the particular homogeneous space of non-reductive type, the so…

The purpose of this survey is to present the recent advances about the Pollicott-Ruelle resonances.

This short note contains elementary evaluations of some Euler sums.

These notes present a systematic treatment of local properties of J-holomorphic maps and of Gromov's convergence for sequences of such maps, specifying the assumptions needed for all statements. In particular, only one auxiliary statement…

This is a survey on stated skein algebras and their representations.

In this note we provide a simple formula of general term of recurrent sequence.

The notes provide a short introduction to de Branges--Rovnyak spaces. They cover some basic facts and are intended to give the reader a taste of the theory, providing sufficient motivation to make it interesting.

These notes are a self-contained short proof of the stability of persistence diagrams.

In this note we answer a question concerning lineability of the set of non-absolutely summing operators.

We establish characterization of $H^1$ Sobolev spaces by certain square functions, improving previous results.

This note is the written version of conversations with young colleagues on unofficial history, general ideas, unexpected facts and open problems concerning tilting theory.

We investigate some types of composition operators, linear and not, and conditions for some spaces to be mapped into themselves and for the operators to satisfy some good properties.

The purpose of these old notes (written in 1998 during a research project on holonomy of pseudo-Riemannian manifolds of type (10,1)) is to determine the orbit structure of the groups Spin(p,q) acting on their spinor spaces for the values…

This is a slightly modified version of the survey article. Minor changes to the text and the references have been made.

These informal notes concern some basic themes of harmonic analysis related to representations of groups.
