Lagrange Institute Thematic Day on Methods: Solutions and Challenges

The format will consist of a sequence of short talks. There will be two types of contributions.

> "Solutions:" 12+3 min talks (problem statement, solution, example application). Solution talks should present methods that potentially have broader application than to the particular subject.

> We will also have time for 5 min "challenges" (interesting unsolved problems for the assembled experts) in case people have ideas.
