Due to the current situation concerning COVID-19 and very uncertain predictions about what will happen in the autumn, after several consultations the organizers of the conference decided to postpone it until the year 2021. We want the event to keep its on-site character, which, however, requires that the pandemic is overcome. The conference date has been changed to 22-25.09.2021, but it is still tentative and subject to revision.


The Conference — devoted to non-classical logics — was initially held in Łódź in September 2008 and 2009.
