We are pleased to announce that the Set Theory, Logic and Topology department of the Alfréd Rényi Institute of Mathematics and Mathematics and the Informatics Committee of the Regional Center of the Hungarian Academy of Sciences in Pécs organize a hybrid workshop celebrating the 5rd World Logic Day on 13th January 2023.

The aim of World Logic Day is nicely summarized by the following quote: 
"A dynamic and global annual celebration of World Logic Day aims at fostering international cooperation, promoting the development of logic, in both research and teaching, supporting the activities of associations, universities and other institutions involved with logic, and enhancing public understanding of logic and its implications for science, technology and innovation."
-- Proclamation of a World Logic Day UNESCO. General Conference, 40th, 2019.

In the spirit of this quote, we aim to organize an event with a friendly atmosphere that inspires fruitful discussions, where researchers and students can get some insights to the works of each-other and can celebrate World Logic day together.
