Seminars
Dept of Math, Seminario II
This seminar is part of the series Topics in Mathematics (https://www.dm.unibo.it/seminari/serials/21), aimed at Math Graduate Students at UNIBO: https://www.dm.unibo.it/seminari/seminars/1811
Seminars
Dip. di Matematica, Aula Bombelli
Second part of some seminars on work by Marshall and Sundberg, C. Bishop, B. Boe.
Seminars
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
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

Seminars
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.
Seminars
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
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.

Interpolation sequences in general RKHS
Seminars
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.
Seminars
Aula Bombelli, Dipartimento di Matematica, Piazza di Porta San Donato 5, 40126, Bologna
Interpolating sequences for the Nevanlinna class will be used to discuss a natural problem on finitely generated ideals in the class.
