Fredholm Properties of Unbounded Operators on Interpolation Spaces,operator between compatible couples. If .. and .. are everywhere defined and bounded, then we obtain the operators usually considered in the classical interpolation theory. As an example, we study differential operators on different ..-spaces induced by the same differential expression.

Bisectors, Isometries and Connected Components in Hilbert Spaces, where .., P. denote respectively the orthogonal projections in . on . and on .. For . ε .(.) such that ker (.. + P. − I) = {0} the . of . and . is a uniquely determined element of .(.) such that (setting .(.) = . and .. = 2.. − .). A mapping Π of .(.) into itself is called an isometry if . This pap

Bisectors, Isometries and Connected Components in Hilbert Spaces,er may be considered as a sequel to [.]) since it relies heavily on the notion of bisector defined therein, as well as the notation and several results proved in that earlier work, in order to determine the arcwise connected components of .(.) and the properties of isometry on that space. This leads to a number of applications to linear relations.
