SUMMARY:2026 Workshop on Topological Combinatorics
DESCRIPTION:The 2026 Workshop on Topological Combinatorics will be held from June 28 to July 11\, 2026 at Gwangju Institute of Science and Technology (GIST)\, located in Gwangju in the southwest of Republic of Korea.  \nThe workshop aims to bring together researchers interested in applications of topology to combinatorics and related areas. This will be the fifth workshop in a series initiated by Ron Aharoni (August 2018 in Shantou\, July 2019 in Prague\, July 2020 on Zoom\, and June 2024 in Paris). \nThe first week (June 28 – July 04) will be reserved for presentations\, while the following days (July 05 – July 11) will be for discussion and collaborations.  \nThe campus offers a variety of amenities\, including a guesthouse that can accommodate approximately 20 guests. \nIn addition\, various lodging options are available within a 15–20 minute walking distance. \nWe are planning to provide accommodation for all invited participants\, and we are also considering offering partial travel support for those with limited funding. \n\nWebsite: https://sites.google.com/view/2026topocomb
