DIMACS Workshop on Applications of Lattices and Ordered Sets to
     Computer Science

July 8 - 10, 2003
DIMACS Center, CoRE Building, Rutgers University

      Jonathan Farley, Massachusetts Institute of Technology 
      Mel Janowitz, DIMACS / Rutgers University, melj at 
      Jimmie Lawson, Louisiana State University, lawson at 
      Michael Mislove, Tulane University, mwm at 

Presented under the auspices of the DIMACS Special Focus
on Mathematics and the Foundations of Computer & Information Science.

                Further information see:

Lattices and ordered sets play an important role in many areas of
computer science. These range from lattices as models for logics,
which are fundamental to understanding computation, to the ordered
sets as models for computation, to the role both lattices and ordered
sets play in combinatorics, a fundamental aspect of computation. In
addition, many applications utilize lattices and ordered sets in
fundamental ways. These include such areas as knowledge
representation, text categorization and data mining, where order plays
a fundamental organizing principle, to the use of lattices and ordered
sets to analyze crypto-protocols in security, to inductive logic
programming, where ordered sets form basic models. A number of more
esoteric structures, such as Kleene algebras and quantales, also
feature in recent advances to understanding computation. This workshop
will bring researchers from the many areas which rely on lattices and
ordered sets together with those doing research in these and related
structures, in order to accomplish two goals:

1) to survey the many areas of computation where lattices and ordered
   sets play a role in order to better understand the problems common
   across these areas, and

2) to enhance the interactions between researchers in the areas of
   lattice theory and ordered sets, and those who utilize these
   structures in modeling computation and in areas of application.

It is expected that researchers in lattice theory and ordered sets
will benefit by discovering new and interesting problems where their
expertise can be applied, and those who work on applications will have
a chance to learn of new advances in these areas that could be applied
to problems where lattice theory and ordered sets traditionally have
played an important role. In addition to these goals, the intention
also is to present talks which are accessible to the broader public
that will help those working in related areas to understand the role
lattice theory and ordered sets play in theoretical computation and
its applications.

The workshop will feature several plenary lectures, whose goal will be
to give a broad background to the workshop, These lectures will be
complimented by several shorter talks that focus on particular areas
of application, as well as on recent advances in lattice theory and
ordered sets. The talks by leaders in lattice theory and ordered sets
will focus on applications to computer science, while the talks by
leading researchers in these areas will describe how techniques from
lattice theory and ordered sets have recently led to results and
applications to problems in computation.
