The 43rd Kolloquium über Kombinatorik (KolKom) will be held on

November 13–14, 2026 at IMOS (TU Berlin)

hosted by the Zuse Institute Berlin and the Technische Universität Berlin. Plenary lectures will be given by Maria Axenovich, Matthew Kwan, Monique Laurent, and Mohit Singh, with contributed talks across two days. Submissions, in the form of short extended abstracts, are now open and welcome from all areas of combinatorics and discrete mathematics, including extremal and probabilistic methods, structural graph theory, algebraic combinatorics, and combinatorial optimization.

Contributed talks are 20 minutes plus 5 minutes for questions and are welcome from all areas of combinatorics and discrete mathematics. To propose one, submit a single PDF compiled from the LaTeX template: a one-paragraph short abstract followed by a roughly two-page extended abstract (references excluded). The deadline is end of day on September 30, 2026, with decisions by October 9.

Submitting requires an OpenReview account. Please create one early: profiles registered with an institutional email address are activated immediately, while others can take up to two weeks to be approved.

Organized by Christoph Spiegel (Zuse Institute Berlin). For inquiries, please contact spiegel@zib.de.

Details on travel and accommodation will be posted here.
