Theoretical Foundations and Numerical Methods for Sparse Recovery

ARGOMENTI: International Area

Annunce of the Summer School on "Theoretical Foundations and Numerical Methods for Sparse Recovery" which will be held at the Johann Radon Institute for Computational and Applied Mathematics (RICAM), Linz - Austria, on August 31 - September 4, 2009.

The School is addressed to graduate students and early stage researchers. The Program of the School and Important Notices are briefly illustrated below.

Sparsity has become a very important concept in recent years in applied mathematics, especially in mathematical signal and image processing, in the numerical treatment of PDEs as well as in inverse problems. The key idea is that many types of functions and signals arising naturally in these contexts can be described by only a small number of significant degrees of freedom. Clearly, one should take advantage of this feature in order to design very efficient ad hoc numerical solutions based on a drastic dimensionality reduction. This intensive School aims at describing the novel ideas that have emerged in sparse recovery with emphasis on theoretical foundations and numerical methodologies.

-Important notices on accomodation and inscription
Linz is the European Capital of Culture for the year 2009. The accommodations in town are limited. Unfortunately for this reason we will be able to host a limited number of external participants. We recommend you to take the following actions as soon as possible:
* Before sending your inscription we warmly recommend you to check the
availability of an accommodation at the local hotel list and to reserve a room as soon as possible;
* The deadline for the inscription to the school is June 30, 2009. The inscription request should be submitted with an informal email to Andreas Langer (; your email should be entitled "Inscription to the Summer School on sparsity";
* Ph.D. students and early stage researchers are invited to present together with their inscription a request of financial support to cover the local expenses in case it is needed; we will provide such a support for a limited number of participants, possibly for all.
