Liverpool Discrete Mathematics Colloquium

2nd-3rd September 2025

University of Liverpool

About

This two day Colloquium aims to bring together researchers in discrete mathematics, from areas such as structural and algorithmic graph theory, extremal combinatorics, logic and foundations of Computer Science.

There is a four-hour tutorial on Constraint Satisfaction Problems given by Andrei Krokhin (Durham), nine invited talks, and a session with contributed one slide pitches by junior researchers.

Venue

All talks will be held in the Ashton Lecture Room which is on the First floor of the Ashton Building, The University of Liverpool, Brownlow Street, Liverpool, L3 3GJ

The venue is wheelchair accessable, and a 15 minute walk from Liverpool Lime street (main train station).

Catering

There are tea/coffee breaks provided. Lunches are not provided, however there is the University of Liverpool refectory and plenty of local cafes and restaurants nearby.

There will be a conference dinner on the evening of the first day. All participants are welcome to attend, however non-speaking participants will have to cover the cost of their own meal.

Funding for Students

We urge all students to keep receipts for expenses as we may be able to refund some expenses after the conference.

Registration

Attendance at the Liverpool Discrete Mathematics Colloquium is free of charge. However, registration is required (deadline 25th August 2025) to help us with logisics, and to ensure adequate arrangements for the coffee/tea breaks.
