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:** Math Tower P-131**Organizers:** Xiuxiong Chen , Marcus Khuri and Claude LeBrun

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 4:00pm - 5:30pm**Location:** Math Tower P-131**Organizers:** Robert Lazarsfeld and Olivier Martin

Weekly seminar for the algebraic geometry group.

**Time:** Thu 1:15pm - 2:30pm**Location:** Math Tower P-131**Organizers:** Christopher Bishop, Theodore Drivas, Bob Hough, Raanan Schul

The analysis seminar covers a wide range of topics which can broadly be interpreted as "analysis". These include, for example, Probability; Analytic Number Theory; Geometric Function Theory; Geometric Measure Theory; Harmonic Analysis; Computational Geometry; Metric Geometry; Quasiconformal and Quasisymmetric Mappings; Several Complex Variables; and Partial Differential Equations.

**Time:** Thu 4:30pm - 5:30pm**Location:** Math Tower P-131**Organizers****:** Jingrui Cheng, Theo Drivas, Bob Hough, Robert Lazarsfeld

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

Seminar on Topology,geometry, discretization and algorithms

**Time:** Fri 12:20pm - 2:20pm**Location:** Math Tower 4-130**Organizers:** Dennis Sullivan

Combinatorial topology and exterior algebra combine to create a spatial discretization optimally compatible with differential forms , multi vector fields and their algebraic symmetries. Computational algorithms related to nonlinear PDE can be naturally formulated. Other speakers will report on Navier Stokes and 3D fluid computations.
