Interpolation for predefined types(abstract)
We give a logic-independent semantics for predefined (data) types
within the categorical abstract model theoretic framework of the
theory of institutions. For this semantics we develop a generic
interpolation result which can be easily applied to various concrete
situations from the theory and practice of specification and
programming. Our study of interpolation is motivated by a number of
important applications to computing science especially in the area of
structured specifications.
