==============================================================================

This scientific meeting is the sixth in a series of annual workshops 
focusing on topics of higher order logic theorem proving, its usage 
in the HOL system and its applications. Previous workshops took
place in Cambridge UK, Aarhus Denmark, Davis USA and Leuven Belgium.

The HOL system is a higher order logic theorem proving system originally 
implemented at Cambridge University.  It has found many applications, from 
verification of hardware designs at various levels to verification of 
software and communication protocols. Besides HOL, contributions and 
experiences with other implementations of higher order logic, and 
comparison between HOL and other theorem-provers are also invited.

TOPICS. 
=======

The program committee invites papers related to all topics concerning 
higher order logic theorem proving and its applications in HOL and/or 
other higher order logic based theorem provers. Topics include, but 
are not limited to, the following:

 * Extensions/enhancements of the HOL system;

 * Other formalisms in comparison with the HOL
   formulation of higher-order logic;

 * Other theorem-provers in comparison with the
   HOL system;

 * Applications of the HOL system;

 * Implementation issues (e.g. efficiency, integrity,
   usability, interoperability) for the HOL system
   and other related systems.

Submissions to the workshop will be reviewed by external referees and
an international program committee (to be announced). Potential authors 
are invited to submit full papers, with at most 4500 words, describing 
recent research. Papers discussing work in progress are also strongly 
encouraged, but should be clearly marked as such. Submissions must contain 
contact information (contact person, email address, phone number, and 
postal address), a 150-word abstract, and the paper category (research 
or progress report).

To accelerate 
the review process, submissions are to be made electronically by sending 
Postscript via email to the address given below. Authors should ensure 
that their submissions can be printed on BOTH A4 and 11x8.5 inch paper.
Electronic submissions will be acknowledged when received. If you are unable
to send the submission electronically, please contact the Program Chair
in advance of the submission deadline, May 1, 1993.

chair before June 1st, 1993.


IMPORTANT DATES

 * Deadline for paper submissions:   May 1, 1993: 
 * Notification of acceptance:       June 7, 1993: 
 * Camera ready copy for 
   published proceedings:            July 15, 1993:

Workshop Proceedings
===================

Accepted papers will be made available to workshop participants. The
program committee is also seeking a publisher for a proceedings of this 
workshop. Previous workshop proceedings have been published by IEEE 
Computer Society and North-Holland respectively.


Other Events
============

A two-day introductory course on the HOL system is planned for August 9-10.
There is also a possibility of one or more other related courses planned 
for August 9 and/or August 10.

Additionally, a three-day introductory on formal hardware verification 
covering both HOL-based methods as well as other approaches such as model 
checking and symbolic simulation is planned for August 4-6. This course 
is organized separately from HUG'93, however, it has been scheduled in 
conjunction with HUG'93 for the convenience of those who may wish to 
participate in both events.

Students Bursary
================

The program committee is actively seeking external financial supports
to students participants. A limited number of awards to student authors 
might be available. Student authors who intend to apply for this support 
should state so in their cover letters, sent along with their submissions.

Location
========

The University of British Columbia is located on a peninsula, adjoining 
the city of Vancouver, which has a population of approximately 1 million.
The setting for the city is one of the most beautiful in the world,
and outdoor sports ranging from skiing to sailing to hiking are a few
minutes away from the campus. The city itself is quite cosmopolitan, 
with many different ethnic groups represented. The climate during
August is moderate (daytime average is 23C) with a lot sunshine.
