Theoretical Fluid Dynamics
This textbook gives an introduction to fluid dynamics based on flows for which analytical solutions exist, like individual vortices, vortex streets, vortex sheets, accretions disks, wakes, jets, cavities, shallow water waves, bores, tides, linear and non-linear free-surface waves, capillary waves, internal gravity waves and shocks. Advanced mathematical techniques ("calculus") are introduced and applied to obtain these solutions, mostly from complex function theory (Schwarz-Christoffel theorem and Wiener-Hopf technique), exterior calculus, singularity theory, asymptotic analysis, the theory of linear and nonlinear integral equations and the theory of characteristics. Many of the derivations, so far contained only in research journals, are made available here to a wider public.
Introduction to Arnold’s Proof of the Kolmogorov–Arnold–Moser Theorem
INTRODUCTION TO ARNOLD’S PROOF OF THE KOLMOGOROV–ARNOLD–MOSER THEOREM This book provides an accessible step-by-step account of Arnold’s classical proof of the Kolmogorov–Arnold–Moser (KAM) Theorem. It begins with a general background of the theorem, proves the famous Liouville–Arnold theorem for integrable systems and introduces Kneser’s tori in four-dimensional phase space. It then introduces and discusses the ideas and techniques used in Arnold’s proof, before the second half of the book walks the reader through a detailed account of Arnold’s proof with all the required steps. It will be a useful guide for advanced students of mathematical physics, in addition to resear...
Instability and Variability of Hot-Star Winds
This specialized workshop was conceived during the workshop on "Non isotropic and Variable Outflows from Stars", which was held at the Space Telescope Science Institute in October, 1991. At that meeting, the four of us collectively decided that the time was ripe for an even more focussed discussion of the basic issues in the area of hot-star wind instability and its observable manifestations. Not that the big problems have been solved! Rather, we are currently in a phase of rapid development, both with regard to the models and to the observations. The key issue at this new workshop would be to decide how the time-dependent structures observed in hot-star winds (e. g. , NACs, DACs, blobs, clu...
Stellar Astrophysics for the Local Group
A review of the new subject of extragalactic stellar astrophysics - for both graduate students and researchers working in astrophysics.
Theoretische Mechanik
Nur selten gelangt NATURBESCHREIBUNG als mathematische Erfassung realer Vorgaenge zu solcher Einheit wie in der Mechanik. Newtons Axiom F=ma fuer den Massenpunkt entfaltet sich zu den Euler-Lagrangeschen und Hamiltonschen Bewegungsgleichungen und schliesslich zum Liouvilleschen Satz fuer den Phasenraumfluss. Die parallele Entwicklung in der Mathematik fuehrt von der Analysis im R^3 ueber die Variationsrechnung zu differenzierbaren Mannigfaltigkeiten. Das Buch gliedert diese Theorie in ueberschaubare formale Schritte -- jedes Argument ist kuerzer als eine Textzeile -- und versucht durch dieses "formelhafte" Vorgehen das Erlernen des Stoffs zu erleichtern.
Thermal and Ionization Aspects of Flows from Hot Stars, Observations and Theory
Annotation The August 1999 workshop discussed studies of the thermal and ionization structure of winds and flows from hot stars that seek to understand the physical processes that lead to instabilities and shocks in the winds, explain the observed mass loss rates and wind velocities, and develop diagnostic methods to analyze the observations. Among the topics of the 51 papers are spectroscopic monitoring of luminous hot stars of the Magellanic Clouds, modeling and diagnostics of smooth winds, counting blobs in Wolf-Rayet winds, and observations of hot stellar winds in symbiotic systems.
