**Spring 2021 Seminars**

The list of currently online seminars is available HERE.

Note: This list is only available to members of Stony Brook University.

**Time:** Tue 4:30pm - 6:00pm**Location:** Online**Organizers:** Claude LeBrun and Xiuxiong Chen

A traditional central focus of the seminar is global Riemannian geometry. However, many other differential-geometric topics, such as symplectic topology, contact geometry, several complex variables, complex algebraic geometry, and General Relativity have all been the focus of many previous talks. The lectures are intended for a broad audience of mathematicians, and we encourage our speakers to begin their talks at an easily accessible, colloquium-style level.

**Time:** Wed 3:00pm - 4:15pm**Location:** Online**Organizers:** Robert Lazarsfeld and Olivier Martin

Weekly seminar for the algebraic geometry group.

**Time:** Thu 4:30pm - 5:30pm**Location:** Online**Organizers****:** Robert Lazarsfeld, Bob Hough, Dzmitry Dudko

The colloquium is intended for a general mathematical audience, including graduate students and researchers from all fields of mathematics.

**Time:** Fri 11:00am - 12:00pm**Location:** Online**Organizers:** Willie Rush Lim and Karina Cho

This seminar is an opportunity for any graduate student to practice giving a good talk on any topic they find particularly interesting. We will have an array of speakers from all years of graduate study, and topics will cover a broad range of Mathematics.

Student Algebraic Geometry Seminar

**Time:** Fri 2:30pm - 3:30pm**Location:** Online**Organizers:** Mads Villadsen and Lisa Marquand

The Student Algebraic Geometry seminar this semester will be on the topic of Positivity, following Robert Lazarsfeld's books. The first part of the seminar will be on the foundational theory of positivity for line bundles, and should be accessible to those new to AG as well. Later in the seminar we might discuss positivity for vector bundles of higher rank, or multiplier ideal sheaves.
