We are glad to announce that the 4th workshop on the HSCR will be held in hybrid form. The situation in the Czech Republic is still far from ideal, but there is now reasonable prospect of a gradual improvement coupled with ongoing vaccination of the population. It thus seems quite likely that we will be able to meet in person and participate at the event fully. The small scale of the workshop allows us to implement safety precautions and at the same time not let these precautions disrupt the comfort of the participants. There will also be an option to participate via online access if you experience travel or other problems due to the pandemics. Please check this website for updates and further information. We will reevaluate our decision before the summer, and will stay positive in spirit until then.
