                    Categories in Computer Science and Logic
                                   June 14 - 20, 1987,  
                          University of Colorado, Boulder

A Joint Summer Research Conference in the Mathematical Sciences, sponsored by 
AMS-IMS-SIAM, and contingent on funding by the NSF.

Category theory has had important uses in logic since the invention of
topos theory sixteen years ago, and logic has always been an important
component of theoretical computer science.  What is new is the increasing
direct interaction between category theory and computer science.  The aim 
of this conference is to bring together researchers who are working on the 
interconnections between category theory and computer science or
between category theory and logic.  The conference will emphasize how
the general machinery developed in category theory can be applied to
specific questions and utilized for category-theoretic studies of
concrete issues.

There is a kernel of topics relevant to all three fields.  It includes, for
example, algebraic theories, Horn logic, lambda calculus, normal form
reductions, and categorical models for computability theory.  Such topics
will be the central focus of the conference, but time will also be provided
for category-theoretic topics presently related either to logic or to
computer science.  On the logic side, these include semantical (algebraic
or topos-theoretic) approaches to proof-theoretic questions, problems
concerning the internal properties of specific objects in (pre-) topoi and
their representations, and categorical sharpening of model-theoretic
notions.  Category theory is useful in studying the proof theory and model
theory of various non-classical logics as well as classical first order
logic.  At the base of many uses of topos theory is the fact that certain
involved mathematical objects (frequently described in terms of
equivariance or continuity in additional parameters) may be viewed as the
interpretation, in a suitable category, of objects of a simpler nature.  On
the computer science side, it has recently been recognized that category
theory is appropriate for formalizing many aspects of computer
programming and program design.  One reason for this is that in computer
science it is necessary to consider many different structures at the same
time.  These structures must be viewed from different aspects and the
interactions between them are a central component of program design.
Category theory is specifically designed to deal with this kind of a
situation on an abstract level.  Specific areas where active research is
going on include:  semantics of programming languages, data type
specifications, categorical programming , and categorical logic.
