#### Organizational Meeting

###### Sungwoo Nam (Illinois Math)

Abstract: We will have an organizational meeting for this semester. This involves making a plan for this semester and possibly choose a topic for a reading seminar. If you want to speak this semester, or are interested in a reading seminar, please join us and make a suggestion.

#### Introduction to moduli spaces of sheaves

###### Sungwoo Nam (Illinois Math)

Abstract: This talk will be an introduction to moduli spaces of sheaves. We will see some motivating questions that lead to the study of moduli spaces of sheaves, and discuss examples telling us why the notion of stability is needed, even in the simplest case of vector bundles on curves. Then I will survey some results on moduli spaces of sheaves on surfaces, especially those of K3 and abelian surfaces and applications to holomorphic symplectic geometry.

#### Deformation and Obstruction for moduli of sheaves

###### Lutian Zhao (Illinois Math)

Abstract: In this talk, I’ll introduce the deformation theory for moduli of sheaves,. I’ll give a proof for the description of tangent space of moduli of sheaves and the condition for which this moduli space is smooth. The final goal of this talk is to introduce the construction for Simpson’s moduli space of sheaves.
