EFFIE PAPAGEORGIOU (U. of Crete): LARGE SETS CONTAINING NO COPIES OF A GIVEN INFINITE SEQUENCE

Seminario I - In presence and online event

Let A be a discrete, unbounded, infinite set in R. Can we find a "large" measurable set E in R which does not contain any affine copy x + tA of A (for any in R, t > 0)? https://www.dm.unibo.it/seminari/mat/seminars/3052/print

Martino Lupini, On the classification of continuous trace C*-algebras and their (phantom) automorphisms

Seminario II - In presence and online event

I will recall the notion of continuous trace C*-algebra, and present classical classification results in terms of the Cech cohomology of the spectrum. I will then explain how the framework of Borel-definable homological algebra allows one to refine the analysis and obtain more precise results.

Fausto Di Biase (U. Pescara), On the differentiation of integrals in measure spaces along filters

Seminario II

THE RANDOM FOREST ALGORITHM AND RELATED REPRODUCING KERNELS II, Nicola Arcozzi

Seminario I - In presence and online event

The reproducing kernel introduced in the first seminar, and the corresponding Hilbert space structure, are studied using tools from Fourier theory on finite abelian groups.

Pavel Mozolyako (Saint Petersburg State University), The weighted Hardy operator on the poly-tree

Seminario II - In presence and online event

Isidoros Iakovidis: THE RANDOM FOREST ALGORITHM AND RELATED REPRODUCING KERNELS I

Seminario II - In presence and online event

In 2015 the consistency of the random forest algorithm was linked to a particular reproducing kernel. In the first of some expository talks, I introduce the algorithm and the kernel in question.

GEOMETRIC TOOLS IN FUNCTION THEORY (AND THE HEISENBERG GROUP) V, Nicola Arcozzi

Seminario I - In presence and online event

5th and last. The horocycles in the hyperbolic disc carry the structure of a commutative group, hence a (crucial) notion of Fourier transform. In the complex ball, the corresponding (Heisenberg) group is noncommutative, hence its Fourier theory is more twisted, although not less crucial.

GEOMETRIC TOOLS IN FUNCTION THEORY (AND THE HEISENBERG GROUP) IV, Nicola Arcozzi

Seminario I - In presence and online event

4th in this series of expository seminars. We leave the complex world and discuss some geometric aspects of the Heisenberg group (Riemannian and sub-Riemannian) per se: geodesics, metric spheres, horizontal curves, consequences of the two-step structure of the group.
