Abstract We derive lower bounds on the maximal lengthλ s(n) of (n, s) Davenport Schinzel sequences. These bounds have the form λ2s=1(n)=Ω(nαs(n)), whereα(n) is the extremely slowly growing functional inverse of the Ackermann function. These bounds extend the nonlinear lower boundλ 3 (n)=Ω(nα(n)) due to Hart and Sharir [5], and are obtained by an inductive construction based upon the construction given in [5].
