  Title: On Algebraic Surfaces
  Abstract: I will quickly discuss the most important invariants on compact complex surfaces. There is a fairly complete description of all classes of surfaces classified by Federigo Enriques and Kunihiko Kodaira, except the ones of general type. I will state the classification of algebraic surfaces and then discuss moduli of surfaces of general type.
  
  
• February 27: Szu-Yin Yeh
  Title: Quasi-conformal mappings and quasi-symmetric mappings.
  Abstract: I will start with an introduction of quasiconformal mappings and quasisymmetric mappings. Then I will talk about their extension problems. For example, when does a quasiconformal mapping on a domain D in the Euclidean space R^n have a quasiconformal extension to R^n?
  
  
• March 20: Chia-Yen Tsai
  Title: From your closet to Teichmuller space.
  Abstract: This will be an introduction to Teichmuller space and the mapping class group. Instead of giving definitions, I will explain how to "see" the space. Continuing the same idea, we will see how the mapping class group acts on Teichmuller space. In particular, we will talk about the action of pseudo-Anosov mapping classes, which are non-periodic and irreducible. To obtain more intuition, I will construct some pseudo-Anosov mapping classes. On the other hand, we will use couple methods to check if a given mapping class is pseudo-Anosov.
  
  
• April 3: Aleksandra (Ola) Kwiatkowska
  Title: Actions and Boolean actions of Polish groups.
  Abstract: I will first give some examples of Polish groups. We consider actions of Polish groups on a measure space and measure preserving Boolean actions (we act on measurable sets modulo null sets instead of on points). The natural question is whether a Boolean action arises from an action. I will give an overview of some known results.
