The main theme of this minisymposium is the analysis of piecewise-smooth dynamical systems and their bifurcations. Specifically, it has been shown that the system dynamics undergo dramatic changes when, by varying the parameters, the system trajectory (or part of it) becomes tangent to one of the boundaries dividing the phase space into different regions associated with different (smooth) system configurations. This novel type of bifurcations, termed order-collision (Nusse & Yorke 1992) and grazing (Nordmark 1991), have been shown to organise the dynamical behaviour of several systems of relevance in applications such as power electronic converters, vibro-impacting mechanical devices, and friction oscillators. The speakers will discuss their latest results in this area and present some examples of relevance in applications.
