AECC – African Enumerative Combinatorics Community
The African Enumerative Combinatorics Community (AECC) brings together students and researchers across Africa with an interest in enumerative combinatorics and related areas.
AECC builds on an earlier regional collaboration in enumerative combinatorics, the Combinatorial Research Studio (CoRS). CoRS was established with support from ISP and Sida bilateral research programmes and brought together researchers from Addis Ababa University, the University of Antananarivo, Makerere University and Mbarara University of Science and Technology, with international collaboration involving Stockholm University and Université Paris Cité.
Seminar series
AECC organises a regular online seminar series in enumerative combinatorics, providing a meeting place for researchers and students across institutions and countries.
