Abstract

We investigate inclusion indices for general function spaces, not necessarily symmetric. Using them, we estimate the grade of proximity between two spaces $E\,{\hookrightarrow}\, F$ when we have certain information on the inclusion. The results are based on ideas from interpolation theory.
