Abstract
The past decade has seen an explosion of work on calculi of explicit substitutions.
Numerous work has illustrated the usefulness of these calculi for practical notions
like the implementation of typed functional programming languages and higher
order proof assistants. Three styles of explicit substitutions are treated in this paper:
the  and the s e which have proved useful for solving practical problems like
higher order uni cation, and the suspension calculus related to the implementation
of the language Prolog. We enlarge the suspension calculus with an adequate eta-
