   We received many further applications for talks and try to arrange the program as convenient as possible. But surely we cannot avoid parallel sessions taking place in the afternoons. Moreover, a small number of talks will be selected in advance and granted an extended length.

   We ask all participants (who have not yet done this) to send us titles & abstracts of their talks by June 15, 2017 (titles) and by August 15, 2017 (abstracts), at latest. There will also be an opportunity for ad hoc -seminars.

   The lecture rooms will be equipped with overhead projector, data projector + laptop, and a small board.

   You can have a look at the (preliminary) list of participants and (in due time) on the corresponding abstracts via our web-site.

2. Venue
   The Conference will take place in the Mathematical Research and Conference Center in Będlewo situated in a beautiful countryside not far from Poznań.
3. Registration
   You will receive a separate Email within the next days where we ask you to confirm and complete your details for the registration. As soon as you reply to this email to us npfsa2017@uni-jena.de your registration becomes binding and we shall reserve the accommodation according to your wishes then. You should reply to this confirmation message by

   Please note, that we cannot guarantee that everyone who applied for a single room can have it, because the total number of rooms is restricted (and we shall have a lot of participants). So please read your confirmation message carefully ! We apologise for any inconvenience this may cause you in advance.

4. Lecture Notes
   We plan to offer all speakers of this conference the possibility to send us their material, slides etc. afterwards (preferably in pdf). Alternatively also a (closely linked) paper would be welcome.

   We collect all this material (or links to your personal web pages) and “publish” it on a special web page of this conference such that participants can download the files.

   You may contact us if you have any question.

5. Costs & Payment
   The accommodation is arranged in single and double rooms with full board (buffet breakfast, lunch and dinner).
