| Research Abstract |
We studied several rewriting systems for proving confluence of higher-order term rewriting systems automatically. In this project, we showed many term rewriting systems of combinators do not have strong head normalization. Furthermore, we presented procedures for disproving two properties of infinitary term rewriting systems. the strong head normalization and the productivity. The correctness of our procedures is proved. And we implemented our procedures.
