Open Dependency Pair Problem 1

Dependency Pairs

a#(p(x, y), z) → a#(y, z)a#(p(x, y), z) → a#(x, z)
a#(a(x, y), z) → a#(y, z)a#(lambda(x), y) → a#(x, p(1, a(y, t)))
a#(a(x, y), z) → a#(x, a(y, z))a#(lambda(x), y) → a#(y, t)

Rewrite Rules

a(lambda(x), y) → lambda(a(x, p(1, a(y, t))))a(p(x, y), z) → p(a(x, z), a(y, z))
a(a(x, y), z) → a(x, a(y, z))a(id, x) → x
a(1, id) → 1a(t, id) → t
a(1, p(x, y)) → xa(t, p(x, y)) → y

Original Signature

Termination of terms over the following signature is verified: id, lambda, 1, t, a, p
