The Panhellenic Logic Symposium is a biennial scientific event that was established in 1997. It aims to promote interaction and cross-fertilization among different areas of logic. Originally conceived as a way of bringing together the many logicians of Hellenic descent throughout the world, the PLS has evolved into an international forum for the communication of state-of-the-art advances in logic. The symposium is open to researchers worldwide who work in logic broadly conceived.
