### 1 Course description

Differential geometry is an important and often indispensable mathematical tool for the formulation of theories in physics. The present course introduces the concepts of differential geometry such as metric and other tensors, tangential vectors, one-forms, manifolds, and charts. In particular, the students acquire the tools necessary to follow subsequent lectures on general relativity. The course focuses on conveying the mathematical framework in modern formulation, but in basic manner for students from physics and other sciences. The concepts are illustrated and motivated throughout by applications in physics, in particular from special relativity, theoretical mechanics and electrodynamics.
