  The workshop is colocated with the ICALP '00 conference, which will
  be held at the University of Geneva.  Accomodations at a very
  special ICALP rate have been reserved in a couple of hotels and very
  inexpensive rooms will be available at the Student Housing.  Lunch
  will be served daily on campus and there will be morning and
  afternoon refreshment breaks.  For more details see the ICALP '00
  web address given above.

  Types support reliable reasoning in many areas such as programming
  languages, logic, linguistics, etc.  A _polymorphic_ type is one
  that stands for some number of instance types.  The use of type
  systems for non-trivial purposes generally requires type

  Intersection types, which were introduced roughly twenty years ago,
  provide type polymorphism by listing type instances.  This differs
  from the more widely used universal types, which provide type
  polymorphism by giving a type scheme that can be instantiated into
  various type instances.  (A similar relationship holds between union
  types and existential types, the duals of intersection types and
  universal types.)

  Intersection types were initially intended for use in analyzing
  and/or synthesizing lambda models as well as in analyzing
  normalization properties.  Over the last twenty years the scope of
  theoretical research on intersection types has broadened (see
  possible topics below).  Recently, there have been a number of
  breakthroughs in the use of intersection types (and similar
  technology) for practical purposes such as program analysis.

  The ITRS '00 workshop will bring together researchers working on
  both the theory and practice of systems with intersection types and
  related systems (e.g., union types, refinement types, etc.).  The
  proceedings will be published by Carleton Scientific; copies will be
  distributed at the workshop.
