NEW: FOR SLIDES CLICK ON TITLE OF TALK | [NEW: PICTURE OF THE CONFERENCE]
Over the last decade one can observe a very important research activity in the field of matrix functions, using tools both from numerical linear algebra and constructive approximation theory. Matrix functions are useful tools not only in applied mathematics and scientific computing, but also in various other fields like control theory, electromagnetism or the research on complex networks like social networks. The present meeting intends to gather specialists from constructive approximation theory, most of them being interested in applications in numerical linear algebra in a broader sense, and matrix functions in particular.
This meeting, being part of the Second Thematic Semester Painlevé-CEMPI-Phlam 2018, is the follow-up of various Lille activities on constructive complex approximation (Journées Approximation 2000, 2004, 2008, 2012, and 2016) and a spring school on matrix functions.

There is no inscription fee, but registration before April 30 is mandatory, please use the following form. The update of the list of participants will be done manually on a regular basis. There will be a poster session. Please let us know as soon as possible and before April 30 if you want to present a poster.
Links to hotels in downtown Lille can be found here and here, please do not wait until the last moment for reservations. The invited speakers will be at Résidence universitaire internationale REEFLEX, a modern Appart-Hotel located on the campus "Cité Scientifique", 4 minutes walking distance from the metro station "Cité Scientifique", and 4 minutes walking distance to the department of mathematics. A limited number of "student residence" rooms might be available for PhD students and PostDocs on the campus, if you are interested in such an economical lodging, please send us quickly a mail.
On Thursday May 31 at 8pm all participants of the conference are warmly invited to attend the conference dinner at the Brasserie de la Paix, 25 place Rihour, in downtown Lille, very close to the Grand Place, metro station Rihour. Please tell us if you prefer vegetarian food for lunch and/or dinner.
On Wednesday May 30 at 8pm we intend to have some joint beer and dinner in the restaurant Trois Brasseurs, 22 place de la Gare, just in front of the railway station Lille Flandres, for those participants who arrive already on time in Lille. Since we have to reserve a table, please write us a mail if you are interested to join us.
