This course is an introduction to Poisson geometry. Poisson geometry is the study of differentiable manifolds equipped with a Poisson bracket. Its roots lie in Classical Mechanics, but it became an independent field of study in the 70’s and in the 80’s, in parallel to its close cousin Symplectic geometry. If you have a basic knowledge of manifolds, vector fields and differential forms, you can get an idea of what Poisson geometry is by reading a brief introduction (under construction). Students taking this course are assumed to know differential geometry at the level of Math 518 – Differentiable Manifolds. Lectures for this topic course will be delivered by Rui Loja Fernandes and Ioan Marcut.

**Grading Policy**

**Expository Paper**Students will be required to write (in LaTeX) and present a paper. The papers will be due by the last week of classes. Presentations will be in class, during the last week of classes.**Problem Sessions**There will be problem sessions every other week. Students are not required to turn in homework, but homework problems will be discussed in these sessions.
