Lie groups and bundles
Lie groups and bundles
Both Lie groups and line bundles are transversal tools that are used in many mathematical fields. We start from a geometrical point view, but the course provides basic tools for students interested in algebraic and differential topology, algebraic geometry and mathematical physics.
