13 p, 241.4 KB Riesz bases of exponentials for convex polytopes with symmetric faces / Debernardi Pinos, Alberto (Bar-Ilan University) ; Lev, Nir (Bar-Ilan University)
We prove that for any convex polytope in arbitrary dimensions which is centrally symmetric and whose faces of all dimensions are also centrally symmetric, there exists a Riesz basis of exponential functions in the space L2(Ω). [...]

7 p, 145.6 KB Gabor orthonormal bases, tiling and periodicity / Debernardi Pinos, Alberto (University of Aveiro. Department of Mathematics) ; Lev, Nir (Bar-Ilan University. Department of Mathematics)
We show that if a Gabor system is an orthonormal basis in for square-summable functions in the real line, and if the window function is compactly supported, then both the time and frequency shift sets must be periodic. [...]

38 p, 355.2 KB Equidistribution estimates for Fekete points on complex manifolds / Lev, Nir ; Ortega Cerdà, Joaquim ; Centre de Recerca Matemàtica
We study the equidistribution of Fekete points in a compact complex manifold. These are extremal point configurations defined through sections of powers of a positive line bundle. Their equidistribution is a known result. [...]
