Within mathematics, approximation theory is such a field: In the past decade, we have seen a host of such new developments: wavelet approximations, fast computational algorithms with applications to turbulence, chaos and fractals; computational efficiencies from scaling similarities, and data.

Within mathematics, approximation theory is such a field: In the past decade, we have seen a host of such new developments: wavelet approximations, fast computational algorithms with applications to turbulence, chaos and fractals; computational efficiencies from scaling similarities, and data compression; and new adaptive non-linear algorithms. The author Achieser of this Dover classic (first published by Ungar in 1956, and reprinted by Dover in 1992) is a pioneer in the approximation theory, and the book is still a very attractive first. I recommend it to students even today!

Kenneth Ira Appel (October 8, 1932 – April 19, 2013) was an American mathematician who in 1976, with colleague Wolfgang Haken at the University of Illinois at Urbana–Champaign, solved one of the most famous problems in mathematics, the four-color theorem. They proved that any two-dimensional map, with certain limitations, can be filled in with four colors without any adjacent "countries" sharing the same color.

Contributions to Group Theory. It is a tribute to Lyndon's mathematical breadth that papers covering such a wide array of topics are all closely related to the work he has done. Several of the articles fall into subfields of combinatorial group theory, areas in which much of the initial work was done by Lyndon. Kenneth I. Appel, John G. Ratc. Contributions to group theory.

The probabilistic theory of random and biased nets is further developed by the tracing method treated previously.

The probabilistic theory of random and biased nets is further developed by the tracing method treated previously. Distribution of closed chain lengths is derived for random nets and for nets with a simple reflexive bias. The island model bias is treated for the case of two islands and a single axon tracing, resulting in a pair of linear difference equations with two indices

Flag as Inappropriate. Contributions to mathematics. Kenneth Appel's other publications include an article with . Schupp titled Artin Groups and Infinite Coxeter Groups.

Flag as Inappropriate. The four color theorem. Kenneth Appel is known for his work in topology, the branch of mathematics that explores certain properties of geometric figures. His biggest accomplishment was proving the four color theorem in 1976 with Wolfgang Haken. In this article Appel and Schupp introduced four theorems that are true about Coxeter groups and then proved them to be true for Artin groups.

It is a tribute to Lyndon's mathematical breadth that papers covering such a wide array of topics are all closely related to the work he has done. Several of the articles fall into subfields of combinatorial group theory, areas in which much of the initial work was done by Lyndon. Remaining research articles fall into various subfields of homological groups, another area in which he has made major contributions. Research articles, written by some of the leading practitioners in the field, are listed below.

There is a biographical essay about Lyndon by Kenneth Appel, and there are expository articles about his work by Saunders MacLane, John Ratcliffe, Jerome Keisler, and Paul Schupp. MacLane describes the results in Lyndon's doctoral thesis and explains how they fit into the early history of spectral sequences while Ratcliffe presents Lyndon's fundamental work in cohomology of groups in the early part of his career. His work in logic, especially his fundamental results in model theory in the mid 1950s is discussed by Keisler. Lyndon's contribution to group theory over the past twenty years is described by Schupp.
