Wednesday 7th at SMDIS

In today's first talk Dr. Paolo Muratore-Ginanneschi (University of Helsinki) discussed the scaling properties of the two-dimensional Navier-Stokes equation, for which the existence and uniqueness of solution still remains without a proof. Paolo pointed out differences between two different theories of the problem, leading to the conclusion that the renormalization theory of two-dimensional fully-developed turbulence in the Navier-Stokes equation needs to be revisited - still work to be done by the participants and colleagues.

In the afternoon, Prof. Olav Tirkkonen (Helsinki University of Technology, Theory and NokiaCo. ) talked about his ongoing work on self-organizing communication networks. In particular, his idea is to draw lessons from statistical physics of synchronization phenomena and apply them to engineering problems related to ad hoc communication networks. In a very lively ex tempore discussion session following Olav's talk, several ideas and connections to earlier work rose from the audience that Tirkkonen and co-workers can exploit - even during the programme (hopefully).
