Seminars

NICOLA ARCOZZI: INTERPOLATING SEQUENCES FOR THE DIRICHLET SPACE II

Dip. di Matematica, Aula Bombelli

Second part of some seminars on work by Marshall and Sundberg, C. Bishop, B. Boe.
01 DECEMBER 2017

Seminars

Dott. Davide Cordella: DISCRETE EXTREMAL LENGTH ON GRAPHS AND SQUARE TILINGS

Dip. di Matematica, Aula Bombelli

Following an article by Oded Schramm (1993), there is a correspondence between planar graphs and square tilings of a rectangle. https://www.dm.unibo.it/seminari/seminars/1803

Seminars

Nicola Arcozzi: INTERPOLATING SEQUENCES FOR THE DIRICHLET SPACE I

Dipartimento di Matematica, Aula Enriques

Interpolating sequences for the holomorphic Dirichlet space and its multiplier space were characterized in two preprints of 1994: Marshall and Sundberg, and Chris Bishop. The plan is going through the details of the proof. https://www.dm.unibo.it/seminari/seminars/1806

Karl-Mikael Perfekt (U. of Reading: THE LAYER POTENTIAL APPROACH TO THE SPECTRA OF TRANSMISSION PROBLEMS ON DOMAINS WITH SINGULARITIES I

10 NOVEMBER 2017

Seminars

Nikolaos Chalmoukis: GENERALIZED INTEGRATION OPERATORS ON HARDY SPACES

Aula da stabilire, Dipartimento di Matematica, Piazza di Porta San Donato 5, 40126, Bologna

We introduce a variant of the generalized Cesaro operator on Hardy spaces and prove results about its boundedness and compactness. As an application we generalize a theorem by Rattya on complex linear differential equations and we prove a result about factorization of derivatives of Hardy functions.
03 NOVEMBER 2017

Seminars

Alessandro Monguzzi (Università di Milano): BEURLING AND LAX THEOREMS ON INVARIANT SUBSPACES

Seminario II, Dipartimento di Matematica, Piazza di Porta San Donato 5, 40126, Bologna

We will present two classical results by Beurling and Lax characterizing invariant subspaces of the shift operator on the Hardy space of the unit disc and of the upper half plane, respectively.

Seminars

Nicola Arcozzi: AN APPLICATION OF ANALYSIS ON TREES: SOME TRACE INEQUALITIES FOR HOLOMORPHIC FUNCTIONS

Aula Enriques, Dipartimento di Matematica, Piazza di Porta San Donato 5, 40126, Bologna

Why doing analysis on trees, besides the intrinsic interest? We show as application the characterization of the Carleson measures (or "trace measures") for the Dirichlet space. The seminar requires virtually no prerequisite on holomorphic functions.

Crash course

Nicola Arcozzi: INTERPOLATION IN REPRODUCING KERNEL HILBERT SPACES - LECTURE 1

Seminario I, Dipartimento di Matematica, Piazza di Porta San Donato 5, 40126, Bologna

Interpolation sequences in general RKHS
20 OCTOBER 2017

Seminars

Matteo Levi: EQUILIBRIUM MEASURES ON TREES

Seminario I, Dipartimento di Matematica, Piazza di Porta San Donato 5 40126, Bologna

On a metric space (X,d) one can define a set function called capacity. To any compact subset E of X can be associated a measure m on X, called equilibrium measure for E, such that m(E)=cap(E). We will give a characterization of equilibrium measures when X is a locally finite tree of infinite depth.
