讲座内容：It’s about a class of macroscopic continuous models with feedback interactions inducing spontaneous vector or nematic polarisation and mechanical deformation of elastic active media. In the former case, the emerging pattern undergoes a slow coarsening process but permanent polarity may emerge when the system is topologically constrained. Oscillatory instabilities arise in active systems on a finite wavelength, and lead to complex wave patterns. Transition to a deformed polarised state may be frustrated in constrained geometry but leads to boundary undulations in free-boundary settings.
