## COURSE DESCRIPTION

Multilinear algebra: tensors and exterior forms. Differential forms on $\mathbf{R}^n$: exterior differentiation, the pull-back operation and the Poincaré lemma. Applications to physics: Maxwell’s equations from the differential form perspective. Integration of forms on open sets of $\mathbf{R}^n$. The change of variables formula revisited. The degree of a differentiable mapping. Differential forms on manifolds and de Rham theory. Integration of forms on manifolds and Stokes’ theorem. The push-forward operation for forms. Thom forms and intersection theory. Applications to differential topology.
