Colloquium di Dipartimento
Date: 11 February 2026
Schedule: 14:30 - Rome Time
Where: Conference Room 1201 "R. Dal Passo "
Speaker: Abstract:
Recently the learning problems took the center stage in area of theoretical computer science. An amazing and beautiful thing is that they are harmonic analysis problems at heart. The lecture concerns with some natural and elementary question of learning theory and the approach to learning via harmonic analysis.
Suppose you wish to find a N by N matrix by asking this matrix question that it honestly answers. For example you can ask question ``What is your (1,1) element?'' Obviously you will need N^2 many questions like that. But if one knows some information on Fourier
side one can ask only log log N questions if they are carefully randomly chosen.
Of course one pays the price: first of all one would find the matrix only with high confidence (high probability bigger than 1-\delta), secondly with the error \epsilon. Such learning is known as PAC learning, PAC stands for `probably approximately correct'.
The origins of the problem are in theoretical computer science, but the methods are pure harmonic analysis and probability. The main ingredient is dimension free Bernstein--Remez inequality.

DIFFERENTIAL EQUATIONS SEMINAR
Date: 10 February 2026
Schedule: 14:30 - Rome Time -
Where: Conference Room "R. Dal Passo "
Title: " Local rigidity of the Suris potential as an integrable standard twist map "
Speaker: Laurent Niederman - Université Paris-Saclay
Abstract:
Numerous orbits exist in the solar system or in astrodynamics with very peculiar motions. Their common feature is that they consist of two moons or satellites around a much heavier central attractor with almost equal semi-major axes, this is called a co-orbital motion. In spite of analytical theories and numerical investigations developed to describe their long-term dynamics, so far very few rigorous long-time stability results in this setting have been obtained even in the restricted three-body problem. Actually, the nearly equal semi major axes of the moons implies also nearly equal orbital periods (or 1:1 mean motion resonance), and this last point prevent the application of the usual Hamiltonian perturbation theory for the three body problem.
Adapting the idea of Arnold to a resonant case, hence by an applcation of KAM theory to the planar planetary three-body problem, we provide a rigorous proof of existence of a large measure set of Lagrangian invariant tori supporting quasi-periodic co-orbital motions, hence stable over infinite times.
