SumTopo is an established conference series since 1986, attracting 120-200 participants annually. As always, this meeting will engage discussion in modern advances in topology through the activities of several special sessions, as well as invited plenary and semi-plenary speakers.
SumTopo 2025 will be held in the Humanities Building at the University of South Alabama in Mobile, AL from August 11-14, with a few additional pre-conference activities happening on August 10. Virtual participation is also supported. For more information, please contact the local organizers (Steven Clontz, Joanna Furno, and Elena Pavelescu) at <sclontz+sumtopo@southalabama.edu>.
We are grateful for the support of the National Science Foundation for this conference.
