While some recent work ha s brought homotopical methods into the theory of zeta functions\, there is in fact a lesser-known zeta function that is native to homotopy theory. N amely\, every suitably finite decomposition space (aka 2-Segal space) admi ts an abstract zeta function as an element of its incidence algebra. In th is talk\, I will show how many 'classical' zeta functions from number theo ry and algebraic geometry can be realized in this homotopical framework\, and outline some preliminary work in progress with Julie Bergner and Matt Feller towards a motivic version of the above story.\n\nThe discussion for Andrew Kobin’s talk is taking place not in zoom-chat\, but at https://t inyurl.com/2020-09-11-ak (and will be deleted after 3-7 days).\n LOCATION:https://researchseminars.org/talk/agstanford/23/ END:VEVENT END:VCALENDAR
