## 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.

**Prerequisites:** 18.101; 18.700 or 18.701
