DETN 2016 - Workshop Dirichlet Forms, Operator Theory and Mathematical Physics
Organised by Ali Ben Amor (Gabes), Christian Seifert (TU Hamburg)
Funded by DAAD
- Date:
- December 5, 2016 - December 9, 2016
(Arrival: December 4, Departure: December 10). - Venue:
- Hotel Medina Belisaire, Hammamet, Tunisia.
(Participants should ask for the all inclusive package. For participants from Germany it may even be more convenient to book an all inclusive package including flight and Hotel via FTI or Schauinsland.)
Program
The schedule can be found here.
We will have 2 main talks by Ali Ben Amor:
- Existence vs blow-up of nonnegative solutions for the perturbed Dirichlet fractional Laplacian.
- The Dirichlet fractional Laplacian with Hardy potentials: Properties of the minimal solution and blow-up.
Furthermore, there will be talks of PhD students:
- Mouldi Seddik: On the perturbation of some positive operators.
- Imen Metoui: Generation of analytic semigroups by generalized Ornstein–Uhlenbeck operators with singular potentials in $L^{p}$-spaces.
- Faten Belgacem: Convergence and spectral asymptotic for the Robin Laplacian at large coupling.
- Jan Meichsner: Fractional Powers of Operators in Banach Spaces.
- Nader Djeridi: The structure of A-m isometric weighted shift.
- Christian Rose: Topology and heat kernels.

Idea of the workshop
The participants are grouped into small teams. Each team has to work through one article, to understand the content and to give a presentation on it. The teams are encouraged to prepare slides for the presentation, which can be uploaded here. Each team has its own page with a discussion forum to ask and/or answer questions on the paper. Additionally, every participant is asked to fill in the details in the List of Participants page by clicking on the edit button on the right.
Everybody interested in this meeting should feel free to contact any of the organisers for further information and/or to pass on information on this meeting!
