Abstract: Our work on complex systems is analyzed by methods from nonlinear dynamics and statistical physics. We are interested in the versatile role of noise such as order-by-disorder effects and novel effects which would be absent without noise. Another fundamental role is played by frustration of interaction loops. We point out why the concept of frustration is generic and more generally applicable than in the familiar context of spin glasses. With examples from coupled oscillatory units we shall illustrate how frustrated couplings can considerably enrich the phase space and lead to similar effects as in spin glasses. We briefly discuss ongoing work on predator-prey games with a dynamic generation of multiple spatial and temporal scales and very interesting applications.
