Aarhus (Denmark), August 25, 2025
Following the success of the first three editions in 2017, 2019, and 2023 RADICAL proposes a workshop aligned within the intersection between concurrency and logic, broadly construed. Admittedly broad, such an intersection has been explored from very diverse angles for many years now. More recently, the interplay of concurrency and logic with areas/applications such as, for instance,
design, verification, synthesis for concurrent systems, both qualitative and quantitative;
strategic reasoning for distributed and multi-agent systems;
analysis and validation techniques for concurrent and distributed programs and systems (e.g., separation logic, advanced type systems, and runtime verification techniques);
has received much attention, as witnessed by recent CONCUR editions. These areas/applications have become increasingly consolidated, and start to have profound impact in neighboring communities such as
programming languages
artificial intelligence
computer security
knowledge representation
As an unfortunate side effect, however, the important unifying role that concurrency plays in all of them seems hard to find in a single scientific event. Indeed, there do not seem to exist appropriate venues in which different research communities interested in concurrency and logic can meet closely, cross-fertilize, and share their most exciting recent results. RADICAL intends to fill a gap between CONCUR researchers that now also typically publish and interact in other different venues; it also aims at attracting researchers from neighboring communities whose work naturally intersects with CONCUR.
AN INNOVATIVE FORMAT: BACK TO THE BASICS
RADICAL will offer an innovative format for a one-day workshop for researchers involved in all aspects of concurrency and logic including, but not limited to, the areas mentioned above.
Distinctive innovative aspects of RADICAL include:
Format:
RADICAL will feature a combination of invited and (short) contributed talks.
We would like to recover the informal character of scientific workshops.
Focus:
Rather than regular paper submissions, authors should submit talk proposals (up to 2 pages, excluding references).
See the submission page for details.
No proceedings:
RADICAL will be an informal venue, oriented to interaction, and so it will have no formal proceedings.
