                August 17 - 28, 1998, Saarbruecken, Germany

This workshop brings together recent work on the design of abstract 
machines for functional programming languages based on logical foundations.  
Abstract machines describe implementations of functional languages on a 
level of abstraction which is high enough to make it possible to reason 
about the implementation but low enough as to allow an easy coding of the 
abstract machine.  The workshop is aimed at students and researchers with a 
basic understanding of functional programming and intuitionistic logic who 
want to work on the exciting field of programming with a solid logical 

We focus the workshop along two main themes: explicit substitutions and 
abstract machines based on Linear Logic.  Most of the more recent work on 
abstract machines is directed towards implementing and proving correct 
functional languages based on Linear Logic ideas.  Linear Logic, being a 
resource logic, was deemed ideal to model resource control in functional 

The workshop consists of five sessions of 90 minutes and time will be 
allocated according to the quality of the submissions.  We seek original 
papers on the full spectrum of abstract machines from theory to 
application.  Among the topics of interest are:

  Theory                                Design and Implementation
  ------                                -------------------------
  formal semantics                      description of working systems
  explicit substitution  calculi        combinators
  type theory                           graph reduction techniques
  linear decorations                    run-time/memory management
  game theory for linear logic          applications
All researchers in the area, but especially Ph.D.  students and young 
researchers, are encouraged to submit an extended abstract (up to 12 pages) 
and preferably in postscript A4 format by
