Dear organizers and participants,

I would like to invite you to the doctoral seminar on this Thursday at 9:50 in S6. I will present a paper:

Pavle V. M. Blagojević, Florian Frick, Günter M. Ziegler //Tverberg plus constraints (arXiv http://arxiv.org/abs/1401.0690)

All proofs presented during the talk will be really simple and short. Only very basic knowledge is assumed - some ideas of simplicial complexes http://en.wikipedia.org/wiki/Simplicial_complex and their join http://en.wikipedia.org/wiki/Join_%28topology%29. (It might be useful to go through this short article http://arxiv.org/abs/math/0307245http://arxiv.org/abs/0809.4040, too.)

Best regards

Vojta Kaluza
