**Description:**

Lie Groups are of central importance in Mathematics and required background for every research mathematician and theoretical physicist. At the nexus of Analysis, Geometry, and Topology, Lie Groups have essential applications to Algebraic and Differential Geometry, Differential Equations, Mathematical Physics, Topology, and many other areas of Mathematics and Physics. This course will give a broad introduction to Lie Groups, with minimal prerequisites. Topics may be modified depending on the audience and their interests but should include: |

1. Classical matrix Lie groups and Lie algebras |

2. Topological, smooth, and analytic manifolds |

3. Group actions on manifolds |

4. Vector fields and the exponential map |

5. Peter-Weyl Theorem |

6. Lie groups and Lie algebras |

7. Baker-Campbell-Hausdorff formula |

8. Structure and representation of complex semi-simple Lie algebras and Lie Groups |

9. Fundamental group of a Lie group |

10. Principle bundles |
