This colloquium provides a forum for experts in applied mathematics and physics, mechanics and engineering (civil, mechanical and electrical) to exchange ideas and get awareness of trends in the analysis and real application of time-periodic systems. A wide range of topics is welcomed, especially these:

• new developments in solution techniques (e.g. homotopy methods, complexification, perturbation techniques),
• continuous structures under axial loads (e.g. beams or rotating shells),
• effects of strong nonlinearity;
• effects of multi-frequency excitation (e.g. quasi-periodic parametric excitation),
• parametric resonance amplification (e.g. for micro-ring gyroscopes, scanning probe microscopy) and
• efficient analysis of complex structures (e.g. Chebyshev approximation of fundamental solutions).
