Buch. Zustand: Neu. Neuware -Travelers differ.At one extreme are random travelers who see what they accidentally bump into.At the other extreme are the lock-step travelers who follow a banner (or a red umbrella) and look when and where a voice tells them to look. Between these extremes are the guide-book travelers who identify the whereabouts of those sites that interest them and they plan their sightseeing accordingly. If a traveler¿s interests are captivated by the arts, guide books can be very helpful. For example, the table of contents of a current guide book for travelers going to G- many has sections on architecture, art, literature, music and cinema.The index gives page references for famous writers, musicians, and artists.Yet, while Germany was a dominate force in physical science during the 19th and into the 20th centuries and while the names and photos of prominent German physical scientists who worked in this period are sprinkled through the pages of textbooks, only one scientist is m- tioned by name:Albert Einstein is identified as the most famous citizen of Ulm.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 260 pp. Englisch.

Buch. Zustand: Neu. Neuware -This volume contains papers written by participants of the 6th Workshop on - erator Theory in Krein Spaces and Operator Polynomials, which was held at the Technische Universit¿ at Berlin, Germany, December 14 to 17, 2006. This workshop was attended by 67 participants from 14 countries. The lectures covered topics from spectral and perturbation theory of linear operators in inner product spaces and from operator polynomials. They included the theory of generalized Nevanlinna and Schur functions, di erential operators, singular perturbations, de Branges spaces, scattering problems, block numerical ranges, nonnegative matrices and relations. All these topics are re ected in the present volume. Besides, it contains an after dinner speech from an earlier wo- shop, which we think may be of interest for the reader, as well as a speech on the occasion of the retirement of Peter Jonas. It is a pleasure to acknowledge the substantial nancial support received from the ¿ Deutsche Forschungsgemeinschaft (DFG), ¿ Berlin Mathematical School (BMS), ¿ DFG-Forschungszentrum MATHEON ¿Mathematik fur ¿ Schlussel- ¿ technologien¿, ¿ Institute of Mathematics of the Technische Universit¿ at Berlin.

In a recent series of papers M.W. Wong has studied a degenerate elliptic partial di erential operator related to the Heisenberg group. It turns out that Wong's example is best understood when replaced in the context of the phase-space Weyl calculus we have developed in previous work; this - proach highlights the relationship of Wong's constructions with the quantum mechanics of charged particles in a uniform magnetic eld. Using Shubin's classes of pseudodi erential symbols we prove global hypoellipticity results for arbitrary phase-space operators arising from elliptic operators on con- uration space.

Buch. Zustand: Neu. Neuware -Charles François Sturm was born in Geneva, Switzerland, on September 29, 1803. He obtained his scientific education in this city and began his rich scientific career there through significant research in sound propagation and compressibility of fluids. In September of 2003, on the occasion of the 200th anniversary of his birth, his home city honoured his worldwide recognition with a colloquium and workshop under the sponsorship of the University of Geneva.This volume is based on lectures presented at that colloquium, which focused on C.F. Sturm's own work. The book contains a selection of reproductions of his scientific publications. Sturm contributed notably to geometry (theory of polygons, elementary geometry, projective geometry, conic sections), algebra, analysis (differential equations, series), optics (caustics, physiological optics), mechanics, and other areas of physics (particularly fluid mechanics and speed of sound in water).Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 820 pp. Englisch.
