In a sense that I will make precise\, 2-Segal sets can be viewed as categorified associative algebras. As a TQFT Club me mber\, you might ask\, “Are there 2-Segal sets that correspond to (commu tative) Frobenius algebras?” The answer is yes\, commutativity and Frobe nius structures come from asking the simplicial set to possess additional compatible structure maps. I’ll give an overview of these correspondence s as well as some background as to how I arrived at this topic from the wo rld of Poisson geometry. This is based on joint works with Ivan Contreras \, Walker Stern\, and Sophia Marx.\n LOCATION:https://researchseminars.org/talk/TQFT/141/ END:VEVENT END:VCALENDAR
