A theorem of Rajan says that a tensor product of irreducible, finite dimensional representations of a simple Lie algebra over a field of characteristic zero determines individual constituents uniquely...
In this talk we study chaotic dynamics generated by analytic convex billiards. We consider the set S of analytic billiards with negative curvature satisfying the following property: for any rational r...
Questa tesi esamina due testi di Archimede dal titolo la Misura del Cerchio e Sui Galleggianti. Sono stati progettati percorsi didattici storico-interdisciplinari a partire dalla lettura dei testi ori...
We consider a symmetrization procedure for convex function in R^n that preserves mixed volumes of the sublevel sets, and for which a Pólya-Szegő type inequality holds. We will obtain a stability impro...
The study of fully faithful functors, including equivalences, between derived categories of smooth projective varieties (or, more generally, smooth proper triangulated categories) is, in many ways, an...
Nel contesto del dibattito sull'innovazione della didattica nella scuola, una iniziativa che si è distinta per capacità di incidere sulla pratica didattica curricolare e per la sua diffusione al livel...
In this talk I will describe the normal stable surfaces with K2=2pg−3 whose only non canonical singularity is a cyclic quotient singularity of type 14k(1,2k−1) and the corresponding locus DD inside th...
The goal of the talk is proving a conjecture of Claude Roger about the universal central extension of the Lie algebra of volume-preserving vector fields. In the beginning we will briefly review the no...
How do we recognize faces? How do we divide people into groups if they are not all friends with each other? How do magnets work? Introduced back in 1982 as a neural network realization of an associati...
We study the evolution in time of smooth sets in the n–dimensional flat torus, such that their boundaries, which are smooth hypersurfaces, move by surface diffusion flow (i.e. the H−1H−1 gradient flow...
