UNIF 2019 - 33rd International Workshop on Unification

June 24, 2019

UNIF 2019 will be the 33rd 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, temporal and description logics
  • 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 2019 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 by clicking here.

UNIF 2019 will be a satellite workshop of Formal Structures for Computation and Deduction (FSCD'19) in Dortmund. Previous editions took place in Oxford/UK (2018 and 2017), Porto/ Portugal (2016), Warsaw/Poland (2015), etc.
