This workshop is in memory of, and in honour of, Pavlos Peppas. Pavlos was a leading researcher in Knowledge Representation and Reasoning (particularly Belief Revision), and a friend, colleague, or mentor to a great many people in the KR community and beyond.

The workshop will tentatively include submitted papers, an invited speaker, and a workshop dinner at a local (Greek, of course) restaurant. Submissions will be reviewed and an informal proceedings posted online.

Submissions may include the following types of papers:

• People who have co-authored papers with Pavlos could present their favourite paper with Pavlos perhaps along with a reflection on Pavlos. Authors may opt to submit an edited summary of the presented work for inclusion in the workshop proceedings.

• People who have published work that builds on one of Pavlos’ publications could present on their publication. As with the preceding, authors may opt to submit an edited summary of the presented work for inclusion in the workshop proceedings.

• Proposals could be received on new work that builds on or references Pavlos’s publications. These would be published in a workshop proceedings.

• Other work that builds on or references Pavlos’s work is welcome. Please contact the organisers if you would like to discuss a possible presentation.

• Subject to consultation and approval of the KR-2025 and NMR-2025 Chairs, a precis of a submission to KR 2025 or NMR 2025 that falls into one of the categories above may be submitted to the workshop.
