  • The essential norm estimates of Hankel and the $\overline\partial$-Neumann operators
    Zeljko Cuckovic, University of Toledo
    venerdì 1 giugno 2018 alle ore 11:00, Sala di Rappresentanza, Università di Milano, Via C. Saldini 50, Milano
    ABSTRACT
    Compactness of the $\overline\partial$-Neumann operator is
    closely connected to the compactness of Hankel operators on the Bergman
    space. At first, for convex domains in $\mathbb{C}^n$, we use the
    $\overline\partial$ methods to relate the compactness of a Hankel
    operator to the boundary behavior of its symbol. In the absence of
    compactness, we give the essential norm estimates of Hankel operators.
    This in turn, led us to obtain the essential norm estimates for the
    $\overline\partial$-Neumann operator on convex domains. (This is joint
    work with Sonmez Sahutoglu)
  • On the harmonicity of slice regular functions
    Cinzia Bisi, Università di Ferrara
    giovedì 31 maggio 2018 alle ore 14:30, Aula Seminari III piano
    ABSTRACT
    I will start improving the definition of slice regular function over the quaternions given by Gentili-Struppa in 2006-2007.
    Then, bringing new ideas to the theory, I will answer positively to the question: is a slice regular function over the quaternions (analogously to a holomorphic function over the complex) ”harmonic” in some sense, i.e. is it in the kernel of some order-two differential operator over the quaternions?
    Finally, I will deduce novel integral formulas as applications.
    This is part of a common project with J. Winkelmann.

  • Tales of Our Forefathers
    Barry Simon, California Institute of Technology
    martedì 29 maggio 2018 alle ore 11:00, Sala Consiglio, 7 piano, Edificio La Nave, Via Bonardi 9
    ABSTRACT
    This is not a mathematics talk but it is a talk for mathematicians. Too often, we think of historical mathematicians as only names assigned to theorems. With vignettes and anecdotes, I’ll convince you they were also human beings and that, as the Chinese say, “May you live in interesting times” really is a curse.
  • SPECTRAL THEORY, SUM RULES AND LARGE DEVIATIONS
    Barry Simon, California Institute of Technology
    lunedì 28 maggio 2018 alle ore 16:30, Aula Chisini, Diparimento di Matematica, Via C. Saldini 50
    ABSTRACT
    After de ning the spectral theory of orthogonal polynomials on the unit circle
    (OPUC) and real line (OPRL), I’ll describe Verblunsky’s version of Szego’s
    theorem as a sum rule for OPUC and the Killip-Simon sum rule for OPRL
    and their spectral consequences. Next I’ll explain the original proof of Killip-Simon using representation theorems for meromorphic Herglotz functions.
    Finally I’ll focus on recent work of Gamboa, Nagel and Rouault who obtain
    the sum rules using large deviations for random matrices.
  • Matrix equation techniques for a class of PDE problems with data uncertainty
    Valeria Simoncini, Dipartimento di Matematica, Alma Mater Studiorum – Universita’ di Bologna
    giovedì 24 maggio 2018 alle ore 11:30,  Aula Consiglio VII Piano – Edificio 14, Dipartimento di Matematica POLITECNICO DI MILANO
    ABSTRACT
    Linear matrix equations arise in an amazingly growing number of applications. Classically, they have been extensively encountered in Control theory and eigenvalue problems. More recently they have been shown to provide a natural platform in the discretization of certain partial differential equations (PDEs), both in the deterministic setting, and in the presence of uncertainty in the data. We first review some numerical techniques for solving various classes of large scale linear matrix equations commonly occurring in applications. Then we focus on recent developments in the solution of (systems of) linear matrix equations associated with the numerical treatment of various stochastic PDE problems.

  • On the Hopf boundary lemma for quasilinear problems involving singular nonlinearities and applications
    Berardino Sciunzi, Università della Calabria
    mercoledì 23 maggio 2018 alle ore 15:15, Aula seminari 3° piano
    ABSTRACT
    We consider positive solutions to quasilinear elliptic problems with singular nonlinearities. We provide a Hopf type boundary lemma via a suitable scaling argument that allows to deal with the lack of regularity of the solutions up to the boundary. Symmetry and monotonicity properties of the solutions follows as an application.
