Inner core anisotropy workshop
We organise a small workshop on the inner core anisotrpy to celebrate the 30th anniversary of the publication of the Nature paper by G. Poupinet , R. Pillet and A. Souriau in 1983. This event will be an opportunity to review current ideas and try to draw new lines of research.
It would take place in Grenoble (ISTerre) the first week of october, Wednesday 2 and Thursday 3 of october. It is free of charge. If you’d like to join (and present your work), please contact Philippe Cardin (philippe.cardin(at)ujf-grenoble.fr) or Sébatien Merkel (sebastien.merkel(at)univ-lille1.fr).
Posters are welcome. The talks will be 20’ long + 10’ discussion. 20’ presentations will be strictly enforced to favor open discussions in the room.
trains from Paris 2/10 7h37-10h43 or 6h37-9h40
trains to Paris 3/10 19h20-22h23
