Structure Meets Power 2026

Aim

There is a remarkable divide in the field of logic in Computer Science between two distinct strands: one focuses on semantics and compositionality (“Structure”), the other on expressiveness and complexity (“Power”). These two traditions are studied by almost disjoint research communities using distinct technical languages and methods.

We believe that bringing these communities and research fields together is an important objective for Computer Science, which may hold the key to fundamental advances in the field. The aim of this workshop is to attract researchers working at the boundary of these two strands, as well as those on either side of the divide who are interested in establishing new connections.

Previous workshops on this theme were held as affiliated workshops of LiCS 2021, ICALP 2022, LiCS 2023 and LiCS 2024. This is a LiCS 2026 affiliated workshop, taking place at FLoC 2026. It will be a hybrid event, however on-site participation is highly encouraged.

Call for Participation

Researchers wishing to give a talk at the workshop are invited to submit an extended abstract of up to three pages (excluding references) describing the key points of the proposed presentation.

Submissions must have a single author, who will be the speaker. co-authors should be clearly credited in the abstract and on the slides.

We encourage submissions at all stages of development, including novel contributions, previously published work, work in progress, and survey-style presentations. Depending on the number of submissions, contributed talks will be 20–30 minutes in length.

Registration

In-person participation is via the main conference registration. Online participation is free.
