（1）Collapsing Geometry of Hyperkaehler Four-Manifolds

Ruobing Zhang is currently an assistant professor at Princeton University. He obtained his Ph.D. at Princeton University in 2016 under the supervision of Alice Chang and Paul Yang. His research focuses on differential geometry and geometric analysis.

(1) Any volume collapsed limit of unit-diameter hyperkaehler metrics on the K3 manifold is isometric to one of the following: the quotient of a flat 3D torus by an involution, a singular special Kaehler metric on the topological 2-sphere, or the unit interval.

(2) Any complete non-compact hyperkaehler 4-manifold with quadratically integrable curvature, namely gravitational instanton, must have one of the following asymptotic model geometries: ALE, ALF, ALG, ALH, ALG* and ALH*.

(3) Any gravitational instanton can be compactified to an open dense subset of certain compact algebraic surface.

With the above classification results, we obtain a rather complete picture of the collapsing geometry of hyperkaehler four manifolds, i.e., classifications of Gromov-Hausdorff limit geometries, tangent cones, singularity formations, as well as all the rescaling bubbles.

Zoom ID：819-3008-5234（密码：983788）

10. Period Relations of Standard L-functions of Symplectic Type

In this talk, I will discuss my work joint with Dihua Jiang and Binyong Sun on the period relation for the twisted standard L-function $L(s, \Pi\otimes\chi)$, where $\Pi$ is an irreducible cuspidal automorphic representation of $GL_{2n}(\mathbb{A})$ which is regular algebraic and of symplectic type.  Along this talk, I will also discuss the key ingredient of this project - the existence of uniform cohomological test vector, which provides the most precise information on the archimedean local integrals.

9. Asymptotics for the matrix-valued Keller-Rubinstein-Sternberg problem

The proof follows the roadmap developed by de Mottoni-Schatzman and Alikakos-Bates-Chen: we first construct an approximate solution solving the regularized system up to arbitrary small terms, and then we prove a spectral lower bound for the linearized operator around it, and finally we estimate the difference between the true solution and the approximate solution. The main difficulties come from the inherent (partially minimal pairing) property of this problem.

This is joint work with Mingwen Fei, Fanghua Lin and Zhifei Zhang.
