Title: Enlargeability and positive scalar curvature on foliations
Abstract: We report recent progress concerning positive scalar curvature on foliations, including generalizations of previous results to the enlargeable foliated spaces.

Title: The Almost Complex Structure on S^6 and Related Schr\odinger Flows
Abstract: In this talk, we report our recent result on the G_2 binormal motion of curves in R^7-
associated to the almost complex structure on S^6 by using the G_2- structure from the
octonions O. The motion is proved to be equivalent to Schr\odinger flows from R^1 to S^6,
and also to a nonlinear Schr\odinger-type system in three unknown complex functions that
generalizes the famous correspondence between the binormal motion of curves in R^3 and
the focusing nonlinear Schr\odinger equation. Some related problems are also discussed.

Title: Compactness and singularity related to harmonic maps
Abstract: In the talk I will review our recent works on compactness and regularity related to harmonic maps, especially on triholomorphic maps between hyperkaehler manifolds.

Title: Inverse mean curvature flow and some geometric applications
Abstract: In this talk, we give some important properties of inverse mean curvature flow for hypersurfaces with nonnegative sectional curvature in a hyperbolic space. By use of the properties of inverse mean curvature flow, we prove some geometric inequalities for such hypersurfaces.
