The fractional Sobolev spaces studied in the book were introduced in the 1950s by Aronszajn, Gagliardo and Slobodeckij in an attempt to fill the gaps between the classical Sobolev spaces. They provide a natural home for solutions of a vast, and rapid

A criterion is obtained for the Hardy-type inequality (∫0a|f(x)|pv(x)dx)1/p≤c1{(v(a)∫0a|f(x)|pdx)1/p+(∫0a∫0a|f(x)−f(y)|pw(|x−y|)dxdy)1/p} to be valid for 0

This chapter is devoted to the study of the Schrödinger operator −Δ + q with q real, and, in particular, the distribution of its eigenvalues. A general result is established on an open subset Ω of Rn using the Max–Min Principle and cover

This chapter is concerned with closable and closed operators in Hilbert spaces, especially with the special classes of symmetric, J-symmetric, accretive and sectorial operators. The Stone–von Neumann theory of extensions of symmetric operators is t

In this chapter, the operators considered are those m-sectorial operators discussed in Chapter VII, and the essential spectra are the sets defined in Chapter IX that remain invariant under compact perturbation. A generalization of a result of Persson

In this chapter, the generalized or weak interpretation of the Dirichlet and Neumann problems for general elliptic expressions is motivated and then the Lax–Milgram Theorem is used to set the problems in the framework of eigenvalue problems for ope

The centre-pieces of this chapter are the Lax–Milgram Theorem and the existence of weak or variational solutions to problems involving sesquilinear forms. An important application is to Kato’s First Representation Theorem, which associates a uniq
