Some properties of Steklov eigenfunctions.

Abstract: I present some results concerning the number of critical points and the number of nodal domains of Steklov eigenfunctions. The results have been obtained in collaboration with Luca Battaglia...

Dalla Didattica Blended alla Didattica Digitale Integrata: sperimentazioni con studenti STEM

Abstract: Farò una veloce panoramica dei miei principali interessi di ricerca focalizzata sui seguenti temi:L’interdisciplinarità nella didattica della MatematicaL’uso delle tecnologie per l’inse...

Puzzling pyramidal molecules: solved problems that raise new questions

Abstract: The mere existence and the spectroscopic behavior of pyramidal molecules like ammonia have remained unsolved problems since the early developments of quantum mechanics. A possible solution c...

Classification of disordered insulators in 1D

Abstract: In this talk I will describe some of the mathematical aspects of disordered topological insulators. These are novel materials which insulate in their bulk but (may) conduct along their edge;...

Upper bounds on the energy of dilute gases of hard-sphere bosons

Abstract: In the last decades, since the first experimental realizations of Bose- Einstein condensates, the study of large bosonic systems has been a very active field of research both in physics...

Some Results on Thompson Groups, Their Unitary Representations, a Knot Construction by Jones, and on some Cuntz Algebras

Abstract: In 2014, Vaughan Jones introduced methods to construct unitary representations of Thomp- son groups F, T, V (from planar algebras or Cuntz algebras) and another to produce knots from th...

Metodi d'alto ordine, preservazione di strutture e riduzione dell'ordine del modello per equazioni alle derivate parziali iperboliche

Abstract: Le equazioni alle derivate parziali iperboliche descrivono numerosi fenomeni fisici e trovare soluzioni analitiche di questi problemi è spesso impossibile. Per questo dobbiamo ricorrere a me...

On the singular fibers of the Hitchin fibration and a Torelli theorem for moduli spaces of principal bundles

Let G be a complex reductive group and C be a complex smooth projective curve of genus at least two. The moduli space of G-Higgs bundles over C has a natural structure of holomorphic symplectic quasi-...

Hypertoric varieties, W-Hilbert schemes and Coulomb branches

Motivated by physics, in the late 1990s Sen discussed a construction of complete hyperkähler metrics in (real) dimension 4 and so-called ALF (asymptotically locally flat) asymptotics as a "superpositi...

Homotopy Associative Submanifolds in G2-manifolds

Associative submanifolds are certain calibrated submanifolds in G2-manifolds. There is the hope that counting them will reveal subtle information about the underlying G2-structure. On the other hand, ...

Sulla classificazione di varietà simplettiche monotone di complessità uno

Spesso molti esempi di varietà simplettiche con azioni Hamiltoniane di gruppi vengono dalla geometria algebrica; questo è il caso, per esempio, per le varietà simplettiche toriche, nelle quali la dime...
