departure: Thursday, October 10

Group pictures of the conference



The workshop is dedicated to the many facets of Delaunay Geometry with an emphasis on discrete geometric structures. Speakers are selected to cover a broad spectrum of perspectives on Delaunay Geometry including (discrete) differential geometry, algorithmic and combinatorial aspects, as well as applications.


The workshop targets by no means not only experts in the field but we especially encourage people from related areas to participate and contribute (with a poster).
