Everything has been said about Stein fillings of lens spaces when they are endowed with their standard (tight) contact structure. Nevertheless, lens spaces support many more tight structures, that are all classified, but for which a complete list of…

3-varietà e rivestimenti ramificati – Simone Cappellini (Università di Pisa)
Titolo: 3-VARIETÀ E RIVESTIMENTI RAMIFICATI Abstract: Lo studio delle 3-varietà è fortemente collegato alla Teoria dei Nodi. In questo seminario ne mostreremo un esempio che passa attraverso lo studio dei rivestimenti ramificati della 3-sfera,…
A deterministic particle approach to aggregation diffusion models and application to opinion dynamics. – Emanuela Radici (Università degli Studi dell’Aquila)
We describe the one dimensional dynamics of a biological population influenced by the presence of a nonlocal attractive potential and a diffusive term, under the constraint that no overcrowding can occur. This setting can be expressed by a class of…
A quantitative Obata theorem via localization – Daniele Semola (Scuola Normale Superiore )
Obata’s theorem characterizes the equality case in the spectral gap inequality for N dimensional Riemannian manifolds with Ricci curvature bounded below by N-1. In this talk I will present an approach to the quantitative study of the shape of…
Triangulated categories of log-motives over a field – Federico Binda (Università di Milano Statale)
In this talk, I will give an overview of the construction of a triangulated category of motives for log smooth log schemes over a field $k$, based on the notion of finite log correspondence, in analogy to Voevodsky’s $\mathsf{DM}(k)$. The affine…
