Book Description
The authors have measured a preliminary value for the branching ratio (Gamma)(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0])/[Gamma](D*[sup +][sub s] --> D[sup +][sub s][gamma]) = 0.0621 [+-] 0.0049(stat) [+-] 0.0063(syst), which is consistent with the previous measurement, but has higher precision. They have also measured [Gamma](D*[sup 0] --> D[sup 0][pi][sup 0])/[Gamma](D*[sup 0] --> D[sup 0][gamma]) = 1.740 [+-] 0.020(stat) [+-] 0.125(syst), which is more precise than, and in agreement with, the world average. The branching fraction B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) = 0.0585 [+-] 0.0043(stat) [+-] 0.0056(syst) is larger than the theoretical prediction, which is in the 1-3% range. However, it should be noted that the theory predicts a strong correlation between B(D*[sup +][sub s] --> D[sup +][sub s][pi][sup 0]) and B(D*[sup +] --> D[sup +][gamma]); for B(D*[sup +] --> D[sup +][gamma]) [approx]1%, B(D*[sup +][sub s] -- D[sup +][sub s][pi][sup 0]) is expected to be greatly enhanced.

Book Description
One of the clearest available introductions to variational methods, this text requires only a minimal background in calculus and linear algebra. Its self-contained treatment explains the application of theoretic notions to the kinds of physical problems that engineers regularly encounter. The text’s first half concerns approximation theoretic notions, exploring the theory and computation of one- and two-dimensional polynomial and other spline functions. Later chapters examine variational methods in the solution of operator equations, focusing on boundary value problems in one and two dimensions. Additional topics include least squares and other Galerkin methods. Many helpful definitions, examples, and exercises appear throughout the book. A classic reference in spline theory, this volume will benefit experts as well as students of engineering and mathematics.

Book Description
In September 1998, during the 'International Workshop on Analysis and Vibrat ing Systems' held in Canmore, Alberta, Canada, it was decided by a group of participants to honour Peter Lancaster on the occasion of his 70th birthday with a volume in the series 'Operator Theory: Advances and Applications'. Friends and colleagues responded enthusiastically to this proposal and within a short time we put together the volume which is now presented to the reader. Regarding accep tance of papers we followed the usual rules of the journal 'Integral Equations and Operator Theory'. The papers are dedicated to different problems in matrix and operator theory, especially to the areas in which Peter contributed so richly. At our request, Peter agreed to write an autobiographical paper, which appears at the beginning of the volume. It continues with the list of Peter's publications. We believe that this volume will pay tribute to Peter on his outstanding achievements in different areas of mathematics. 1. Gohberg, H. Langer P ter Lancast r *1929 Operator Theory: Advances and Applications, Vol. 130, 1- 7 © 2001 Birkhiiuser Verlag Basel/Switzerland My Life and Mathematics Peter Lancaster I was born in Appleby, a small county town in the north of England, on November 14th, 1929. I had two older brothers and was to have one younger sister. My family moved around the north of England as my father's work in an insurance company required.
