An infinite dimensional family of Zoll met rics on the two-dimensional sphere were constructed by Otto Zoll in the be ginning of 1900's\, but many questions about them remain unanswered. In th is talk\, I will explain my motivation to look for higher dimensional anal ogues of Zoll metrics\, where closed geodesics are replaced by embedded mi nimal spheres of codimension one. Then\, I will discuss some recent result s about the construction and geometric understanding of these new geometri es. This is a joint project with F. Marques (Princeton) and A. Neves (UChi cago).\n LOCATION:https://researchseminars.org/talk/Geolis/86/ END:VEVENT END:VCALENDAR
