OBJECTIVES

This meeting is the seventh in a series of annual workshops on higher
order logic theorem proving and its applications, with a primary focus on
the HOL system and similar systems.  Previous workshops were held in
Cambridge, Aarhus, Davis, Leuven, and Vancouver.

Mechanized theorem provers for higher order logic have been applied to many
areas, including design and verification, security, real-time systems,
semantics, compiler verification, program correctness, concurrency, and
program refinement. The theorem proving technology itself is also an active
area of research. This conference will bring together researchers in these
and related areas of investigation for the dissemination and discussion of
new developments in the field.


THE CONFERENCE

The Conference, which will be held in Malta between the 19-22 September,
1994 will consist of morning and afternoon sessions during which invited
papers and refereed papers will be presented and discussed.  Formal
proceedings will be published by Springer Verlag in the Lecture Notes in
Computer Science Series.  Papers discussing work in progress will also be
presented, and will be circulated in an informal participants' proceedings.

The Organising Committee has invited the following guest speakers:

       o Prof. Dr. N.G. de Bruijn (Eindhoven)

            "Highlighting the Lambda-free Fragment of Automath"

       o Dr. Thomas Forster (Cambridge)

            "Weak Systems of Set Theory Related to HOL"

       o Dr. Keith Hanna (Kent)

            "Reasoning about Real Circuits"

THE VENUE

The University of Malta is one of the oldest in Europe, owing its origin to
the Collegium Melitense founded by the Jesuits in 1592.  A new campus at
Msida was opened during the Independence celebrations in 1964, to provide
for the future growth and needs of higher education in Malta.  The
Conference will be held at the Foundation for International Studies which
is housed in the original premises of the Collegium Melitense.

Malta is well connected to all the major European and North African
airports.  London - Malta is a three hour flight and costs approximately US
$350.  Frankfurt or Paris to Malta are two hour flights in a similar price
range to the London flight. Rome-Malta is a one hour flight and should not
cost more than US $230.  Those coming to Malta from outside Europe can do
so via any major airport in Europe, although London often proves easier and
cheaper. The average temperature in Malta in September is 30 degrees
celcius.
