We will s tudy these generating functions by means of their linearised siblings\, so -called 'ask zeta functions'\, obtained by averaging over sizes of kernels in collections of matrices. The study of the latter functions involves a (sometimes surprising!) blend of techniques from algebra\, combinatorics\, and geometry.\n\nVenue: Hybride - UQAM Salle / Room PK-5115\, Pavillon Pr ésident-Kennedy\n \n  \n DTSTART:20250620T193000Z DTEND:20250620T203000Z SUMMARY:Tobias Rossmann (University of Galway) URL:/mathstat/channels/event/tobias-rossmann-universit y-galway-365821 END:VEVENT END:VCALENDAR
