UNIF 2020 - 34th International Workshop on Unification

UNIF 2020: The 34th International Workshop on Unification is part of "Paris Nord Summer of LoVe 2020", a joint event on LOgic and VErification at Université Paris 13, made of Petri Nets 2020, IJCAR 2020, FSCD 2020, and over 20 satellite events.

UNIF 2020 will be the 34th in a series of annual international workshops on unification. Previous editions have taken place mostly in Europe (Austria, Denmark, France, Germany, Ireland, Italy, Poland, UK), but also in the USA and Japan. For more details on previous UNIF workshops, please see the UNIF homepage

Unification is concerned with the problem of making two terms equal, finding solutions for equations, or making formulas equivalent. It is a fundamental process used in a number of fields of computer science, including automated reasoning, term rewriting, logic programming, natural language processing, program analysis, types, etc. Traditionally, the scope of the UNIF workshops has covered the topic of unification in a broad sense, encompassing also research in constraint solving, admissibility of inference rules, and applications such as type checking, query answering and cryptographic protocol analysis.

The objective of this workshop is to bring together theoreticians and practitioners to promote new techniques and results, and to facilitate feedback on the implementation and application of such techniques and results in practice.

Topics of interest to this forum include, but are not limited to:

  • Unification algorithms, calculi and implementations
  • Equational unification and unification modulo theories
  • Admissibility of Inference Rules
  • Unification in modal, fuzzy, temporal and description logics
  • Anti-unification/generalization
  • Semi-unification
  • Narrowing
  • Formalisation of unification
  • Matching Problems
  • Applications
  • Unification in Special Theories
  • Higher-Order Unification
  • Combination problems
  • Contraint Solving
  • Disunification
  • Complexity Issues
  • Type Checking and reconstruction

UNIF 2020 also aims to be a forum for presenting and discussing work in progress, and therefore to provide feedback to authors on their preliminary research. More information about UNIF can be found here.

UNIF 2020 will be a satellite workshop of The International Joint Conference on Automated Reasoning (IJCAR 2020) in Paris, France.

Call for Papers

Following the tradition of UNIF, we call for submissions of abstracts (5 pages) in EasyChair style, to be submitted electronically as PDF through the EasyChair submission site:

Accepted abstracts will be presented at the workshop and included in the informal proceedings of the workshop, available in electronic form as a technical report in the RISC-Linz Report Series from the Research Institute for Symbolic Computation, Johannes Kepler University. At least one of the authors should register for the workshop. 

Based on the number and quality of submissions we will decide whether to organize a special journal issue.

Important Dates:

  • Submission of titles and abstracts: April 13, 2020
  • Submission of full paper:  April 20, 2020
  • Author notification: May 25, 2020
  • Camera-ready papers: June 8, 2020
  • UNIF 2020: June 29, 2020
