Inverse Problems for PDEs (IP2016)
Aims and Scope
The Workshop on Inverse Problems for PDEs (March 29  April 1, 2016) aims to gather researchers working in the broad ﬁeld of inverse problems linked to partial differential equations, providing a place to discuss current directions, novel methods, and future trends in the ﬁeld.
The Workshop topics include, but are not restricted to, parameter identiﬁcation for complex systems governed by partial differential equations, iterative and qualitative methods for domain reconstruction, optimization techniques, inverse eigenvalue problems, as well as the application of inversion algorithms in scientiﬁc, engineering, or industrial problems.
Place and Date
The workshop takes place at the University of Bremen, Germany, during the week after Easter 2016 (Tuesday 29.3.2016 until Friday 1.4.2016).
Organizers
The workshop is organized by the Workgroup on Inverse Problems at the Center of Industrial Mathematics of University of Bremen.
Acknowledgements
The Workshop on Inverse Problems for PDEs 2016 is supported by the Center of Industrial Mathematics of University of Bremen as well as by the Exploratory Project InsideOutsideDuality and Nondestructive Testing granted by the University of Bremen in the framework of its institutional strategy, funded by the excellence initiative of the federal and state governments of Germany.
Registration
Participation in the workshop is free of charge. To simplify the organization of the workshop we nevertheless insist that all participants register in advance by sending a short email to Frederieke Miesner.
Since the number of talks is limited, we might be forced to make a selection among proposed talks, following a firstcomefirstserve rule. Registration for talks is closed!
The workshop features a poster session. Please tell us until February 15March 1, 2016, whether you intend to present a poster and, if so, indicate the title of your poster. There is no limit for posters and the session will be informal.

Location
The workshop takes place in the university building MZH (Mehrzweckhochhaus), the largest building in the central area on the campus. Our rooms on the first floor are MZH 1460 and MZH 1470. All university facilities and university restaurants are nearby.
Here is a map of the university and its surroundings and a list of shops on campus.
Accomodation
There are three hotels on or close to campus:
 The 7THINGS is directly on campus, see this page for its location.
 The Atlantik Hotel Universium, is directly next to campus, see this page for its location.
 The Hotel Munte, is about 5 minutes away from the location of the workshop (walking distance), see this page for its location.
Public Transportation
Bremen has a very well developed public transportation system and we strongly encourage you to use it whenever going, e.g., into town, to the railway station, or to the airport. Maps of the tram and bus system in the city of Bremen can be found here and timetable information is available here.
Purchasing Tickets for the Tram
You can purchase your ticket at a ticket vending machine inside the tram. The ticket machines provide instructions in English and accept banknotes up to 50€ notes. You have to purchase an adult single ticket (EinzelTicket Erwachsene) for 2.70€. If you plan to use the tram frequently, you can buy a ticket for seven days for 21,70€ or ten single tickets for 24,00€ at the BSAG ticket shop outside the central train station (or at tram stop Domsheide) or at the university at Onkel Walter's shop in the central Glashalle (glass hall), see the maker GH in square C2 on the campus plan www.unibremen.de/universitaet/dieuniimueberblick/lageplan.html.
How to Get into Campus
 Tram line number 6 direction “Universität” takes you directly from the central train station and from the Bremen city airport to the university campus (stop "Universität Zentralbereich")
 You can also take the following busses (get off at the stop "Universität Zentralbereich"):
 no. 21 direction “Universität”,
 no. 22 direction “UniversitätLehe”
 no. 31 direction “Upper Borg”
 no. 630 direction “Zeven” or “Tarmstedt” (this is a fast connection)
 no. 670 direction “Worpswede” (this is a fast connection)
Arrival
Arriving by Plane or by Train
 When arriving at the Airport Bremen or at the Central Railway Station (Bremen HBF), then take the tram line 6 in direction “Universität”. This line directly goes into campus and takes about 40 Minutes from the ariport and 20 Minutes from the railway station. It is the fastest and cheapest way to get to campus. Get off at the tram stop “Universität Zentralbereich”.
 Taxi stands can be found both outside the airport and the central station
Arriving by Car
 From the autobahn A1 change at "Bremer Kreuz" to the A27, direction "Cuxhaven/Bremerhaven"
 Take exit number 19 "HornLehe/Universität", follow the direction „Centrum/ Universität“
 At the second intersection turn right into "Universitätsallee" ("University Alley")
 At the next traffic light turn right again into the the "EnriqueSchmidtStraße". Use the the parking lot there. The parking fee is 0.70 Euro per day.
