Title: Fermionic edge states and moving boundaries                                                                                                                                                                                                                                                                                                                                                                                                                                      Abstract: On boundary of some bulk there generically arises edge states localised at the boundary. The play important role in blackhole states, quantum hall states, in ads/cft as well as several other contexts, leading to unexpected behaviour of systems. We will point out origin of these and consider specifically fermionic edge states. We also consider novel situations when the boundaries are time dependent.
