We'll prove the simplest case of Hirzebruch's signature
theorem, which relates the first Pontryagin number of a smooth 4-manifold
to the signature of its intersection form. If time permits, we'll discuss
the more general case of 4k-manifolds. The result is relevant to Prof.
Margalit's ongoing course on characteristic classes of surface bundles.
