■Specialties

term rewriting

■Research Keywords

term rewriting, termination, confluence, and complexity analysis

■Research Interests

Rewriting Techniques for Non-orthogonal Systems
This research project is aimed at developing rewriting techniques for non-terminating and non-orthogonal systems, which are of fundamental importance in declarative programming and theorem proving.
