Real Interpolation of Banach Spaces,t . is continuously embedded into .. The case of an arbitrary compatible couple does not demand any new idea; for a detailed treatment of the general theory, see [BB], [BK], [BL], [BS], [KPS], [Tr]. The results described below are essentially due to N. Aronszjan, E. Gagliardo, J.-L. Lions and J. Peetre.

Unitary Representations and Regularity for Self-adjoint Operators,ne’s theorem states that there is a unique spectral measure . on ?. such that . and this allows one to extend the functional calculus which we already have for functions in . to all Borel functions .. The natural definition of .) for a Borel function . is ., and one may check that for . the two definitions lead to the same operator .).

Some Spaces of Functions and Distributions,tity due to A.P. Calderón giving a representation of a distribution in terms of its derivatives of a fixed order plus a regular term. Finally, we use this representation in order to prove several facts that will be needed in later chapters.
