Börger, Egon (ed.) et al., Computer science logic. 6th workshop, CSL ’92, San Miniato, Italy, September 28 - October 2, 1992. Selected papers. Berlin: Springer-Verlag. Lect. Notes Comput. Sci. 702, 352-378 (1993).
Summary: This paper describes a semantics of typed lambda calculi based on relations. The main mathematical tool is a category-theoretic method of sconing, also called glueing or Freyd covers. Its correspondence to logical relations is also examined.
