Abstract: A CP^1-structure is a geometric structure on a (compact oriented) surface S and its holonomy is a homomorphism from the fundamental group of the surface into PSL(2, C). Moreover it corresponds to a holomorphic quadratic differential on a Riemann surface.

We consider a path C_t of CP^1-structures on S such that C_t diverges to infinity in its deformation space and yet its holonomy converges. We describe its asymptotic behavior of C_t under the assumption the Riemann surface structure on C_t is pinched along a single loop.

Abstract: Motivated by generalizations of the Ginsburg-Landau energy and the diffusion equation in which derivatives are replaced by fractional derivatives, Caffarelli, Roquejoffre, and Savin studied the minimizers of a fractional perimeter functional on sets involving a parameter between 0 and 1. Such minimizers have to satisfy a pointwise condition on their boundary, which can be used to define a notion of nonlocal mean-curvature. This definition only holds for surfaces which are the boundary of a set. I will describe how to define a nonlocal notion of mean-curvature for any surface by introducing a fractional area functional and considering its minimizers. Moreover, I will describe how these ideas can be extended to curves by defining a fractional length and an associated nonlocal curvature for a curve.

Abstract: The rational homotopy groups of the group Diff(S^4) of self-diffeomorphisms of S^4 with the C^\infty-topology. We present a method to prove that there are many 'exotic' non-trivial elements in the rational homotopy groups of Diff(S^4) parametrized by trivalent graphs. The proof utilizes Kontsevich's characteristic classes for smooth disk bundles and a version of clasper surgery for families. In fact, these are analogues of Chern-Simons perturbation theory in 3-dimension and clasper theory due to Goussarov and Habiro.
