DATE TIME ROOM SPEAKER FROM TITLE COMMENT
Wed, 10 Oct 2012 13:15 Z.301 Jose Ignacio Monreal Galan University of Crete The closure in the Bloch norm of Hardy spaces
The proof of a result by Peter Jones on the closure in the Bloch norm of BMOA may be adapted to give a description of the Bloch functions that can be approximated in the Bloch norm by functions in a Hardy space. This result, which depends deeply on the estimations for the Lusin area function proved by Fefferman and Stein, will be proved. Furthermore, we will talk about the closure of bounded analytic functions in Bloch, which is still an open problem.

Wed, 21 Nov 2012 13:15 Z.301 Ioannis Parissis Aalto University A variation norm Carleson theorem for vector-valued Walsh-Fourier series.
I will discuss some recent developments in vector-valued extensions of Carleson's theorem. If $f:\mathbb T,\mathbb R\to X$ is a function that takes values in a Banach space $X$, when do we have that the partial Fourier sums, or integral, converge to the function almost everywhere? Recently, Hytönen and Lacey showed that this theorem is true for the class of intermediate Banach spaces, that is spaces $X=[Y,H]_\theta$ which are complex interpolation spaces between a UMD Banach space $Y$ and a Hilbert space $H$; UMD means that $Y$-valued martingale differences converge unconditionally in the space. In a joint work with Hytönen and Lacey we ``almost characterize`` the Banach spaces $X$ for which a variation norm Carleson theorem holds true for $X$-vaued Walsh-Fourier series, which serve as a dyadic model for the Fourier case. The condition on the space and methods of proof follow the time-frequency analysis of Lacey and Thiele, adjusted to the vector-valued setup. I will also discuss some vector valued extensions of the Bilinear Hilbert Transform and related open problems.
