The theoretical and applied insights of the dynamical systems community into issues where non-smoothness occurs naturally will be brought together in this Colloquium. The major themes would include:

Foundational: Fundamental theory, studies around challenging basic assumptions, geometry, stability, bifurcations, emergent phenomena, development of analytical methods and numerical implementations. Example topics include, but are not limited to perturbations, stochasticity, un-modelled and hidden dynamics.

Applications: Experimental/numerical modeling of instances of vibro-impact and stick-slip dynamics- For instance, heat exchanger tubes, floating ice with rolling ships, rubbing between stator and rotor blades in turbo machinery, hand held percussion machines, loosely fitted joints, gear-pair systems with backlash and free-play, pile drivers, automotive braking, ship mooring lines and fenders etc.
