The Panhellenic Logic Symposium (PLS), a biennial scientific event established in 1997, 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, it 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.

SUBMISSION GUIDELINES
Research papers
The Scientific Committee invites researchers in all areas of logic to submit their papers for presentation at PLS15.
All submitted papers will be reviewed by the Scientific Committee of the symposium, who will make final decisions on acceptance. Accepted papers will appear in an informal, electronic proceedings volume, which will be posted on the event's webpage. During the actual event, each accepted paper should be presented by at least one of its authors.
Papers should be written in English, a maximum of 5 pages long, and prepared (in PDF format) using the EasyChair class style (easychair.org/publications/for_authors). Submissions will happen through EasyChair.
[NEW] After the symposium, the authors of a selection of papers from those presented at PLS 15 will be invited to submit an extended version of their work for a special issue of the Journal of Logical and Algebraic Methods in Programming.

Poster session
Graduate students and early-career researchers are invited to submit a short, 1-page abstract on preliminary work that may not be ready for a full talk yet. Those accepted will be able to present their work in poster form in a special poster session. The session will also feature a mentoring component in which senior researchers will discuss the posters and provide feedback to the authors.
Interested students and early-career researchers should submit their abstracts by
Friday, 29 May 2026
Submissions will be accepted by email at the address
pls15@softlab.ntua.gr
using the email subject [PLS15 poster session]
=====================================================================
[NEW] SHORT SUMMER SCHOOL (Pre-Symposium)
This edition of PLS will host a short summer school during July 2–4, 2026, aimed primarily at students. Participation is open to advanced undergraduates, MSc and PhD students, postdoctoral researchers, and anyone interested in logic. The goal of the summer school is to prepare participants for this year's main tutorials by Maryanthe Malliaris and Alexander S. Kechris.
The Short Summer School will feature A crash course in Model Theory taught by Adele Padgett (University of Vienna). A crash course in Descriptive Set Theory taught by Forte Shinko (UC Berkeley).
In order to attend, please register here: https://forms.gle/rYahrNHjQGeunFBBA
