Workshop on interactions between number theory and wireless communication: York 2014

Monday 19 May 2014, 2.00PM to Friday 23 May 14

The workshop will be held at the University of York during the week 19 to 23 May 2014. The aim of this workshop is to create a fruitful environment for new interdisciplinary collaborations between those working in electronics and number theory. To assist this plenty of time will be set aside for informal discussion. The focused workshop will be held on Tuesday 20 May and Wednesday 21 May and will consist of at most 5 talks per day. On Monday, members of the York number theory group will give a presentation on aspects of Diophantine approximation relevant to recent applications to interference alignment.
