Davenport and A. Schinzel, is a sequence of symbols in which no two adjacent symbols are equal, and it contains no subsequence of the form . Davenport and Schinzel proved that for any natural number, there exists a Davenport-Schinzel sequence of length that uses symbols. In this book, the author constructs a set of segments in the plane whose lower envelope (the pointwise minimum of the segments when viewed as functions of x) consists of subsegments of the segments in the set. The author shows that for each and sufficiently large, there exists a Davenport-Schinzel sequence of length that can be realized by a set of segments. This result settles an open problem in the theory of Davenport-Schinzel sequences and provides a new tool for studying the combinatorial properties of these sequences. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
