Inverse image analysis generalises strictness analysis

A method for analysing the inverse of a first-order functional program is proposed. This method is based on denotational semantics: we analyse the inverse image of a Scott open set under the continuous function which the program denotes. Inverse image analysis is one possible way of extending strictness analysis to languages with lazy data structures and could perhaps be used to optimise code in implementations of such languages.
