More precisely, we show the minimality of a K-invariant Lagrangian submanifold L in a Fano manifold M w.r.t. a globally conformal Kahler metric is equivalent to the minimality of the reduced Lagrangian submanifold L_0=L/K in a Kahler quotient w.r.t. the Hsiang-Lawson metric. Furthermore, we give some examples of Kahler reductions by using a circle action obtained from a chomogenenity one action on a Kahler-Einstein manifold of positive Ricci curvature. Applying these results, we give many examples of minimal Lagrangian submanifolds via reductions.</span><br></div><div><br></div><div><b>13:30-14:30 大仁田義裕</b>（大阪市大，OCAMI）</div><div><br></div><div><b>Title</b>: On Floer homology of the Gauss images of isoparametric hyper surfaces</div><div><br><b>Abstract</b>: Recently we used the Floer homology and the lifted Floer homology for monotone Lagrangian submanifolds in order to study their Hamiltonian non-displaceability<br>(H.
