(1) DecreasingLoopProof (EQUIVALENT transformation)

The following loop(s) give(s) rise to the lower bound Ω(2ⁿ):
The rewrite sequence
mark(terms(X)) →⁺ cons(recip(a__sqr(mark(mark(X)))), terms(s(mark(X))))
gives rise to a decreasing loop by considering the right hand sides subterm at position [0,0,0,0].
The pumping substitution is [X / terms(X)].
The result substitution is [ ].

The rewrite sequence
mark(terms(X)) →⁺ cons(recip(a__sqr(mark(mark(X)))), terms(s(mark(X))))
gives rise to a decreasing loop by considering the right hand sides subterm at position [1,0,0].
The pumping substitution is [X / terms(X)].
The result substitution is [ ].

(27) LowerBoundsProof (EQUIVALENT transformation)

The lowerbound Ω(n¹) was proven with the following lemma:
mark(gen_recip:s:terms:cons:0':nil:first:sqr:add:dbl2_0(n45911_0)) → gen_recip:s:terms:cons:0':nil:first:sqr:add:dbl2_0(n45911_0), rt ∈ Ω(1 + n45911₀)
