Mini-symposia

A mini-symposium is a session of at least five coordinated presentations on a single topic of substantial current interest, in accordance with the scope of the conference.

The session organizers are included in the Scientific Committee and have the responsibility to invite researchers potentially interested in giving a talk in their session.

The duration of talks is 25 minutes, plus 5 minutes for questions and comments.

    Title: Regularization of ill-posed inverse problems

    Abstract: Inverse problems arise in most scientific fields. These problems are usually ill-posed and can be of very large dimension. Developing fast and accurate methods for their solution is of fundamental importance. Moreover, since most methods require the estimation of one or more regularization parameters, the development of automatic strategies for the selection of these parameters is of considerable importance, especially for real-world applications. This minisymposium presents new approaches to the solution of inverse problem and to the automatic estimation of regularization parameters.


  • Maria Carmela De Bonis, Donatella Occorsio
    Title: Approximation methods and applications

    Abstract: The session focuses on new developments and recent advances in the areas of approximation and interpolation of functions, and related methods to approximate integral transforms and solutions of functional equations.


  • Mirjeta Pasha, Lothar Reichel
    Title: Methods for Large-Scale and High-Dimensional Data Analysis

    Abstract: Large-scale computational problems arise from mathematical formulations of applications in science and engineering including medical and astronomical imaging. This minisymposium describes several novel techniques for handling this kind of problems. The solution of discrete ill-posed problems, dynamic problems, as well as quadrature are considered.


  • Michela Redivo Zaglia, Hassane Sadok and Stefano Cipolla
    Title: Recent developments in projection methods with applications

    Abstract: Many existing iterative methods for linear and nonlinear systems of equations exploit, in a way or another, the idea of projecting the original problem into smaller subspaces where a solution can be "easily" computed. Projection Methods have been hugely developed in the last 30 years and represent one of the main computational paradigm in modern scientific computing. The main objective of this session is to bring together researchers with different expertise to discuss and overview novel computational approaches, related to Projection Methods, which target a range of modern large scale applications.


  • Giuseppe Rodriguez, Raf Vandebril
    Title: Large scale techniques in Numerical Linear Algebra

    Abstract: Recently we are facing a serious growth in data from all sorts of applications that needs to be processed. In this session experts in numerical linear algebra will present their research to deal with these immense datasets. Advances in the field will be presented linked to fast and stable linear algebra methods, structure exploiting linear algebra, iterative methods, tensors, dimensionality reduction, fast algorithms, and image processing.

    Title: Recent advances in numerical integration by Gaussian rules

    Abstract: Gaussian formulas occupy a special place in numerical integration. They were introduced in 1814 by the famous German mathematician Carl Friedrich Gauss. They have been intensively developing in various directions. Practical error estimation in these effective formulas is an issue to which special attention is paid, especially in the last 60 years since the introduction of Gauss-Kronrod formulas. It turns out that in many cases the latter formulas cannot be effectively constructed and applied. That was the reason for looking for their alternatives. This mini-symposium is dedicated to recent progress in this area.
