More Properties of Sobolev Embeddings,Various properties of the Sobolev embeddings that feature in the study of partial differential equations are given. These include necessary and suffcient conditions for a Sobolev embedding to be nuclear, and a characterisation of the subspace of a Sobolev space consisting of functions with zero trace.

Elliptic Operators of Arbitrary Order,k solution of the Dirichlet problem. Returning to the Laplace operator, its Dirichlet eigenvalues are considered: Courant’s min-max pronciple is proved together with the analyticity of eigenvectors and the Faber-Krahn inequality for the first eigenvalue. There is a brief discussion of spectral indep
