## Dynamical Systems (2019-2020)

This will be a broad introduction to dynamical systems, intended for upper-level undergraduates and beginning graduate students.

Topics covered in Dynamical Systems I are tentatively planned to include:

- Topological dynamics (transitivity, attractors, chaos, structural stability)
- Ergodic theory (Poincaré recurrence theorem, Birkhoff ergodic theorem, existence of invariant measures)
- Low-dimensional dynamics.

Lecture notes are available here.

## Communication in Mathematics (Autumn 2019)

This course teaches fundamental communication skills in mathematics.

Topics covered include:

- how to write a thesis (more generally, a mathematics paper),
- elementary $\LaTeX$ skills and language conventions,
- how to write a personal statement for Masters and PhD applications.

There are no formal mathematical prerequisites.

This year's course is significantly expanded from last year (which is why it is now worth 2 credit points instead of 1!)

Lecture notes are available here.

## Differential Geometry (2018-2019)

This course was a general introduction to Differential Geometry, intended for upper-level undergraduates and beginning graduate students.

I produced full lecture notes, which can be found here.

- Smooth manifolds, submanifolds, vector fields,
- Lie groups, homogeneous spaces,
- Vector bundles, tensor fields, differential forms,
- Integration on manifolds and the de Rham Theorem,

##### Differential Geometry II (Lectures 28-53):

- Connections on vector bundles, parallel transport, covariant derivatives.
- Curvature and holonomy on vector bundles, Chern-Weil theory.
- Connections and curvature on principal bundles.
- Geodesics and sprays, sectional curvature, Ricci curvature.
- The metric structure of a Riemannian manifold,
- Curvature vs. Topology.

## Algebraic Topology (2017-2018)
