Extremal eigenvalue problems is an actively developing area of spectral geometry.

I will talk about the problems on Riemannian surfaces related to determining metrics of fixed area which maximise a given Laplace eigenvalue.

I will give a short survey on the subject, and outline an approach to extremal problems via the direct method of calculus of variations.
