Talk Title: Results and problems on Dedekind sums
Abstract: Under the influence of B. Riemann, R. Dedekind was interested in the behavior of the function η(z). More specifically, he examined the action of the modular group SL₂(ℤ) on the Poincaré half-plane. These sums play a crucial role in number theory... Read More

Talk Title: On q-Analogues of Bernoulli Numbers and Polynomials
Abstract: This talk will present various q-analogues of Bernoulli numbers and polynomials. We will also introduce a new approach that allows for the re-derivation of the Carlitz version of q-Bernoulli numbers... Read More
Prof. Mehdi Salah
Specialist in Representation Theory & Harmonic Analysis
University of Lorraine, France
Prof. Salah is a Full Professor at the Université de Lorraine and Head of the "Analysis and Number Theory" research group. His research focuses on geometric and algebraic aspects of representation theory of Lie algebras and Lie groups, as well as harmonic and spectral analysis on homogeneous spaces.
Talk Title: Representation theoretic spectrum of locally symmetric spaces
Abstract: The Laplace–Beltrami operator on a compact Riemannian manifold is self-adjoint with a discrete spectrum. Nevertheless, on a pseudo-Riemannian manifold, the situation is much more complicated. We will focus on the case of double cosets Gamma\G/H... Read More
Dr. Zelaci Hacen
Specialist in Algebraic Geometry
University of Eloued, Algeria
Dr. Hacen is a member of the Department of Mathematics at the University of El Oued. His research focuses on algebraic geometry, especially the geometry of moduli spaces of vector bundles and Higgs bundles over curves. He is particularly interested in parahoric G-torsors and the Hitchin system.
Talk Title: Moduli Spaces of Γ-invariant Vector Bundles
Abstract: In this talk, we explore the moduli spaces of semistable Γ-invariant vector bundles on a smooth complex curve X, where Γ is a finite group acting via a Galois cover X→Y. We focus in particular on the connected components of these moduli spaces... Read More
