# Taipei Postdoc Seminar

## Jan. 19 (Wed.) 14:00-15:00 Albert Wood (NTU) Venue: Lecture Hall 5F, Cosmology Building, NTU Title: Gluing Constructions in Geometric Analysis

Abstract:
Over the past 40 years, gluing constructions have become ubiquitous in geometric analysis, giving us new examples of compact manifolds with holonomy G_2 (Joyce), constant mean curvature surfaces (Kapouleas), and more recently, novel translating solutions to Lagrangian mean curvature flow (Su). In this talk, I hope to give an accessible overview of the philosophy of gluing constructions, through the example of finding Calabi-Yau metrics on the K3 surface. The talk will mainly follow the expository article 'Calabi-Yau Metrics on the K3 Surface as a Model Gluing Problem' by Donaldson.

### The Taipei Postdoc Seminar is a weekly seminar that is organized jointly by the Institute of Mathematics of Academia Sinica and the National Center for Theoretical Sciences during the regular academic year. The seminar is held in these two mathematical institutions, with each one of them hosting the event approximately once every two weeks. The National Taiwan University, Academia Sinica, and the NCTS, together employ a significant number of postdoctoral fellows in mathematics from all over the world every year. The diverse scientific and cultural backgrounds of these postdocs create a unique environment of learning, and the goal of the Taipei Postdoc Seminar is to take advantage of this opportunity by bringing together all these postdocs once in a week in an informal-style seminar to enhance discussions and exchange of ideas among the participants. It is our belief that not only will this seminar encourage and eventually lead to more collaboration among mathematicians in Taipei, but it will also give the participants a chance to broaden their own scientific viewpoints. It is our hope that this seminar will greatly enrich the academic experience of the postdoctoral fellows during their stay in Taipei. Organizers: Jun-Wen Peng (wayne.peng@ncts.tw), Yi-Sheng Wang (yisheng@gate.sinica.edu.tw)
