In these models we deal with coupled pairs consisting of a map between manifolds and a spinorial field along this map. Originated from supersymmetric sigma models and supermanifold theory, they are recently analysed using the tools in nonlinear…

Finite Energy Weak Solutions of the Navier-Stokes-Korteweg equations. – Stefano Spirito (Univ. L’Aquila)
In this talk I will present some results concerning the analysis of finite energy weak solutions of the Navier-Stokes-Korteweg equations, which model the dynamic of a viscous compressible fluid with diffuse interface. A general theory of global…
Higher order spectral symbols and eigenvalues approximation for Toeplitz matrices – Giovanni Barbarino (Scuola Normale Superiore)
Room: Sala Seminari Est, Dipartimento di Informatica Abstract. When modeling natural phenomena with linear partial differential equations, the discretized system of equations is generally represented by a sequence of matrices, often coupled with a…
Innovazione tecnologica e mondo del lavoro – Marina Pescini (Accenture)
Accenture è una grande multinazionale che impiega quasi 500.000 persone nel mondo, di cui più di 13.000 in Italia, dove…
Exponential PDE’s in high dimension – Pierpaolo Esposito (Università di Roma, Tor Vergata)
In dimension n elliptic PDE’s with an exponential non-linearity can have a critical behavior when the differential operator either involves derivatives of order >2 or is quasi-linear. Due to intrinsic invariances such PDE’s present a natural lack of…
On the Plateau-Douglas problem for the Willmore energy – Marco Pozzetta (Universita’ di Pisa)
In this talk we will introduce the Willmore energy of surfaces in the three-dimensional euclidean space, which is the surface integral of the squared mean curvature. For a smooth closed embedded planar curve, we will consider the minimization of the…
Matematici nell’editoria scolastica – Martha Fabbri (Mondadori)
Una panoramica del mercato per la scuola secondaria di primo e secondo grado, la filiera di produzione di un testo…
Minimization of the eigenvalues of the Dirichlet-Laplacian with a diameter constraint. – Ilaria Lucardesi (Institut Elie Cartan de Lorraine)
In this talk I present some recent results about the minimization of $\lambda_k$ under diameter constraint. After providing existence, attained at a constant width body, and optimality conditions in any dimension, I focus my attention on the…
A minimization approach to the wave equation on time-dependent domains. – Lucia De Luca (Università di Pisa)
We prove the existence of weak solutions to the homogeneous wave equation on a suitable class of time-dependent domains. Using the approach suggested by De Giorgi and developed by Serra and Tilli, such solutions are approximated by minimizers of…
Il matematico in classe – Pietro di Martino (Delegato del Rettore per la formazione insegnanti)
Nel corso dell’incontro saranno illustrate le opportunità e le modalità per diventare insegnante di scuola secondaria (di primo e secondo…
