### Courses

Each year the department offers four undergraduate courses and nine graduate courses in geometry and topology.

The undergraduate courses,

• Math 433 Introduction to Differential Geometry

• Math 490 Introduction to Topology

are largely taken by undergraduate concentrators in Mathematics, Natural Sciences and Engineering.

The undergraduate courses,

• Math 531 Transformation Groups in Geometry

• Math 590 Introduction to Topology

are taken by undergraduate concentrators in Mathematics, Natural Sciences and Engineering and also by graduate students, usually from departments other than the Mathematics Department. There is a 4 semester sequence of introductory graduate courses in geometry and topology.

• Math 591 Differentiable Manifolds

• Math 592 Introduction to Algebraic Topology

• Math 635 Differential Geometry

• Math 695 Algebraic Topology I

Topics classes,

• Math 636 Topics in Differential Geometry

• Math 696 Topics in Algebraic Topology

• Math 697 Topics in Topology

are offered. Usually, each year Math 636 and 697 are offered twice, and Math 696 is offered once. Occasional topics courses with other numbers are also offered. Recent topics include:

• Introduction to Rigidity Theory (W17, Spatzier)

• Quiver Varieties (W17, Ruan)

• Dynamics and geometry (F16, Spatzier)

• Equivariant Algebraic Topology (F16, Kriz)

• Introduction to Riemann Surfaces (F16, Ji)

• Symplectic Geometry and Integrable Systems (W16, Burns)

• Teichmuller Space vs Symmetric Space (W16, Ji)

• Dynamics and geometry (F15, Spatzier)

• Teichmuller Theory and its Generalizations (F15, Canary)

#### Seminars

The geometry/topology group has four seminars held weekly during the Fall and Winter terms. These are the Geometry Seminar, Topology Seminar, RTG Seminar and Complex Dynamics Seminar. These are informal forums which welcome talks on any topic of geometric interest. Participants include mathematics faculty and graduate students. The schedules are available by cllicking on the name of the appropriate seminar.
