3rd GAMM Juniors' Summer School (September 5 - 9, 2016)

The topic of the GAMM Juniors' School on Applied Mathematics and Mechanics (SAMM) are Geometric Methods in Multi-Body and Structural Dynamics Modelling, Simulation and Control.

This summerschool introduces variational integrators and Lie-group integrators from the basics, emphasizing their geometrical properties.

Then, optimal control is combined with these structure preserving integrators, in order to exploit the natural coupling between mathematical modeling, numerical integration and control.

These methods are exemplarily applied to mechanical multi-body systems. The extensions to structural dynamics, non-smooth systems (e.g. elastic collisions) and electrical systems are outlined.

The topic is presented by two experts in the field and two invited guest speakers. In addition to the lectures there will be example classes.

Who can attend?
The school is open to international PhD and advanced undergraduate students from engineering sciences or mathematics. Please register until the 26th of August 2016 (latest).

A limited number of scholarships was available. These scholarships cover the lodging including full board. Because of the restricted number of such scholarships, we ask students to preferentially use funds available at their home institutions.



The workshop takes place in the "Wilhelm-Ostwald-Park" near Leipzig (Saxony).
