![]() Free Download Analysis and Algebra on Differentiable Manifolds: A Workbook for Students and Teachers by P. M. Gadea , J. Muñoz Masqué English | PDF (True) | 2001 | 446 Pages | ISBN : 904813563X | 4 MB A famous Swiss professor gave a student's course in Basel on Riemann surfaces. After a couple of lectures, a student asked him, "Professor, you have as yet not given an exact de nition of a Riemann surface." The professor answered, "With Riemann surfaces, the main thing is to UNDERSTAND them, not to de ne them." The student's objection was reasonable. From a formal viewpoint, it is of course necessary to start as soon as possible with strict de nitions, but the professor's - swer also has a substantial background. The pure de nition of a Riemann surface- as a complex 1-dimensional complex analytic manifold-contributes little to a true understanding. It takes a long time to really be familiar with what a Riemann s- face is. This example is typical for the objects of global analysis-manifolds with str- tures. There are complex concrete de nitions but these do not automatically explain what they really are, what we can do with them, which operations they really admit, how rigid they are. Hence, there arises the natural question-how to attain a deeper understanding? One well-known way to gain an understanding is through underpinning the d- nitions, theorems and constructions with hierarchies of examples, counterexamples and exercises. Their choice, construction and logical order is for any teacher in global analysis an interesting, important and fun creating task. ![]() Free Download Analog Filters in Nanometer CMOS by Heimo Uhrmann , Robert Kolm , Horst Zimmermann English | PDF (True) | 2014 | 173 Pages | ISBN : 3642380123 | 4.9 MB Starting from the basics of analog filters and the poor transistor characteristics in nanometer CMOS 10 high-performance analog filters developed by the authors in 120 nm and 65 nm CMOS are described extensively. Among them are gm-C filters, current-mode filters, and active filters for system-on-chip realization for Bluetooth, WCDMA, UWB, DVB-H, and LTE applications. For the active filters several operational amplifier designs are described. The book, furthermore, contains a review of the newest state of research on low-voltage low-power analog filters. To cover the topic of the book comprehensively, linearization issues and measurement methods for the characterization of advanced analog filters are introduced in addition. Numerous elaborate illustrations promote an easy comprehension. This book will be of value to engineers and researchers in industry as well as scientists and Ph.D students at universities. The book is also recommendable to graduate students specializing on nanoelectronics, microelectronics or circuit engineering. ![]() Free Download An intellectually gifted insurgent: Diary of an extra-terrestrial Earthling By Abel Abelson 2017 | 272 Pages | ISBN: 1547186046 | EPUB | 1 MB THIS EDITION HAS BEEN REPLACED BY "Setting free the intellectually gifted: Diary of an extra-terrestrial Earthling" (http://amzn.to/1TXD8OK), ASIN B01D7VZDC8, ISBN 978-1530637133.Please buy the new edition instead. ![]() Free Download An Tagen wie diesen: Berühmte Songzeilen und ihre Geschichte By Günther Fischer; Manfred Prescher 2016 | 238 Pages | ISBN: 3806233888 | EPUB | 1 MB Songzeilen und ihre wahre Geschichte: Jeder von uns kennt Liedzeilen, die einem nicht mehr aus dem Kopf gehen, die man mit einem besonderen Ereignis verbindet oder die einfach nur seltsam findet.

The rst is the quantum theory describing the micro-world of elementary p- ticles, the second is the theory of gravity that concerns properties of macroscopic systems such as stars, galaxies, and the universe. The relativistic theory of gr- itation which is known as general relativity was created, at the beginning of the last century, by more or less a single man from pure idea combinations and bold guessing. The task was to "marry" the theory of gravity with the theory of special relativity. The rst attempts were aimed at considering the gravitational potential as a eld in Minkowski space-time. All those attempts failed; it took 10 years until Einstein nally solved the problem. The dif culty was that the old theory of gravity as well as the young theory of special relativity had to be modi ed. The next 50 years were dif cult for this theory because its experimental basis remained weak and its complicated mathematical structure was not well understood. However, in the subsequent period this theory ourished. Thanks to improvements in the te- nology and to the big progress in the methods of astronomical observations, the amount of observable facts to which general relativity is applicable was consid- ably enlarged. This is why general relativity is, today, one of the best experimentally tested theories while many competing theories could be disproved. Also the conc- tual and mathematical fundamentals are better understood now. ![]() Free Download An Introduction to the Kähler-Ricci Flow by Sebastien Boucksom, Philippe Eyssidieux, Vincent Guedj English | PDF (True) | 2013 | 342 Pages | ISBN : 3319008188 | 2.8 MB This volume collects lecture notes from courses offered at several conferences and workshops, and provides the first exposition in book form of the basic theory of the Kähler-Ricci flow and its current state-of-the-art. While several excellent books on Kähler-Einstein geometry are available, there have been no such works on the Kähler-Ricci flow. The book will serve as a valuable resource for graduate students and researchers in complex differential geometry, complex algebraic geometry and Riemannian geometry, and will hopefully foster further developments in this fascinating area of research. ![]() Free Download An Introduction to Semiclassical and Microlocal Analysis by André Martinez English | PDF | 2002 | 193 Pages | ISBN : 0387953442 | 11.2 MB The following lecture notes correspond to a course taught for several years, first at the University of Paris-Nord (France) and then at the University of Bologna (Italy). They are mainly addressed to nonspecialists in the subject, and their purpose is to present in a pedagogical way most of the techniques used in the microlocal treatment of semiclassical problems coming from quantum physics. Both the standard Coo pseudodifferential calculus and the analytic microlocal analysis are developed, in a context that remains intentionally global so that only the relevant difficulties of the theory are encountered. The main original ity lies in the fact that we derive all the main features of analytic microlocal analysis from a single a priori estimate, which turns out to be elementary once the Coo pseudodifferential calculus is established. Various detailed exercises are given at the end of the main chapters, most of them being easily solvable by students. Besides illustrating the main results of the lecture, their aim is also to introduce the reader to various further developments of the theory, such as the functional calculus of pseudodifferential operators, properties of the analytic wave front set, Gevrey classes, the use of coherent states, the notion of semiclassical measures, WKB constructions. Applications to the study of the Schrodinger operator are also discussed in the text, so that they may help the understanding of new notions or general results where they appear by replacing them in the context of quantum mechanics. ![]() Free Download An Introduction to Optimal Control by Yury Shestopalov, Elena Pronina English | 2023 | ISBN: 1527528804 | 261 Pages | PDF | 8.57 MB |
