3rd Call for Abstracts/Participation
                              UNIF 2001
               15th International Workshop on Unification
                           June 18-19, 2001
                            Siena,  Italy
                          Part of IJCAR 2001


UNIF is the main international meeting on unification. Unification
is concerned with the problem of identifying given terms, either 
syntactically or modulo a given logical theory. Syntactic unification
is the basic operation of most automated reasoning systems, and 
unification modulo theories can be used, for instance, to build in 
special equational theories into theorem provers. 

The main purpose of UNIF is to bring together people interested in 
unification, present recent (even unfinished) work, and discuss new 
ideas and trends in unification and related fields. In particular, it
is intended to offer a good opportunity for young researchers and 
researchers working in related areas to get an overview of the current
state of the art in unification theory and get in contact with the 
experts in the field.

UNIF 2001 will be held in June 2001 in Siena, Italy in the context of 
IJCAR 2001, the International Joint Conference on Automated Reasoning
(http://www.dii.unisi.it/~ijcar/).

The meeting will include short (15 minute) and long (30 minute) talks,
invited talks, panel discussions, and social time to discuss current 
topics of interest, which include (but are not limited to): 

   o  General E-unification and Calculi 
   o  Special Unification Algorithms
   o  Matching 
   o  Narrowing 
   o  Higher-Order Unification 
   o  Combination problems 
   o  Disunification 
   o  Typed Unification 
   o  Constraint Solving 
   o  Unification Calculi 
   o  Applications 
   o  Implementations 
   o  Type Checking and Reconstruction 
   o  Unification-Based approaches to Grammar 
   o  Applications
   o  Implementations

The abstract should be written in LaTeX2e with the following settings:
11pt, one column, a4paper and standard margins. 

What to submit:
1. A postscript version of the abstract 
2. A single file containing the LaTeX2e source of the abstract 
   together with all the non-standard macros used in it.

Junior Researcher Travel Award
------------------------------
Thanks to the support of the National Science Foundation, the UNIF
2001 organizing committee offers a number of travel awards. The award
is intended to cover much of the expenses for up to four university
students or post-docs working in the field of unification. The
committee will favorably consider applicants who will be playing an
active role at the workshop by giving a talk. Preference will be given
to applicants from a United States institution, but applications from
deserving young researchers in other countries will be considered as
well.
