Classical res ults say that balls _minimize_ the Newton capacity among bodies of given v olume\, but _maximize_ it among bodies of given diameter. While  the lower bound on capacity in  terms of volume is a cornerstone  of potential theo ry\,  the upper bound in terms of diameter (proved by Szego in 1930) was l argely relegated to a footnote. Recently isodiametric shape optimization f or Riesz capacities has become interesting in the context of aggregation p roblems with pair interactions  of attractive-repulsive type. In this talk I will discuss situations where the capacity-maximizer is not a ball. Whe n does symmetry-breaking occur\, and what are good candidates for non-radi al maximizers?\n\nLocation: Hybride - CRM\, Salle / Room 6214\, Pavillon A ndré Aisenstadt\n DTSTART:20260508T193000Z DTEND:20260508T203000Z SUMMARY:Almut Burchard (University of Toronto) URL:/channels/channels/event/almut-burchard-university -toronto-372803 END:VEVENT END:VCALENDAR
