DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/34/">An
 alogues of Zoll surfaces in minimal surface theory</a>\nby Lucas Ambrozio 
 (IMPA) as part of B.O.W.L Geometry Seminar\n\n\nAbstract\nAbout 121 years 
 ago\, Otto Zoll described a large family of rotationally symmetric Riemann
 ian two-dimensional spheres whose geodesics are all closed and have the sa
 me period. Since then\, a very rich (but yet incomplete) theory developed 
 in order to construct and understand geometries (in a broad sense) with th
 ese special geodesic flows\, also in higher dimensions. \n\nAfter working 
 on certain systolic questions about minimal two-dimensional spheres in thr
 ee-dimensional Riemannian spheres with R. Montezuma (UFC)\, and motivated 
 by other interesting geometric reasons\, I became convinced that another s
 ort of higher dimensional generalisation of Zoll surfaces\, within the the
 ory of minimal submanifolds\, deserved to be investigated on its own. In t
 his talk\, we will report on some of the results we proved about these new
  objects\, including existence results\, together with F. Codá Marques (P
 rinceton) and A. Neves (UChicago).\n
