"And what's the use," proposal Alice, "of a e-book with out photographs or conversations in it?" -Lewis Carroll This e-book is written for modem undergraduate scholars - now not the proper stu­ dents that arithmetic professors want for (and who sometimes grace our campuses), however the scholars like many the writer has taught: gifted yet ap­ preciating evaluation and reinforcement of prior path paintings; prepared to work flat out, yet challenging context and motivation for the maths they're studying. to fit this viewers, the writer eschews density of themes and potency of presentation in prefer of a gentler tone, a coherent tale, digressions on mathe­ maticians, physicists and their notations, easy examples labored out intimately, and reinforcement of the fundamentals. Dense and effective texts play a very important function within the schooling of budding (and budded) mathematicians and physicists. This booklet doesn't presume to enhance at the classics in that style. quite, it goals to supply these classics with a wide new iteration of appreciative readers. this article introduces a few easy constructs of recent symplectic geometry within the context of an outdated celestial mechanics challenge, the two-body challenge. We current the derivation of Kepler's legislation of planetary movement from Newton's legislation of gravitation, first within the sort of an undergraduate physics path, and x Preface in spite of this within the language of symplectic geometry. No past publicity to symplectic geometry is needed: we introduce and illustrate all important con­ structs.

By Pavel Grinfeld

This textbook is distinct from different texts at the topic via the intensity of the presentation and the dialogue of the calculus of relocating surfaces, that is an extension of tensor calculus to deforming manifolds.

 

Designed for complicated undergraduate and graduate scholars, this article invitations its viewers to take a clean examine formerly realized fabric throughout the prism of tensor calculus. as soon as the framework is mastered, the coed is brought to new fabric which include differential geometry on manifolds, form optimization, boundary perturbation and dynamic fluid movie equations.

 

The language of tensors, initially championed by means of Einstein, is as primary because the languages of calculus and linear algebra and is one who each technical scientist should converse. The tensor method, invented on the flip of the 20th century, is now thought of classical. but, because the writer indicates, it is still remarkably very important and suitable. The author’s expert lecturing services are glaring by way of the inclusion of insightful examples and a plethora of routines. loads of fabric is dedicated to the geometric basics, the mechanics of swap of variables, the right kind use of the tensor notation and the dialogue of the interaction among algebra and geometry. The early chapters have many phrases and few equations. The definition of a tensor comes purely in bankruptcy 6 – whilst the reader is prepared for it. whereas this article keeps a constant point of rigor, it takes nice care to prevent formalizing the subject.

 

The final a part of the textbook is dedicated to the Calculus of relocating Surfaces. it's the first textbook exposition of this crucial approach and is likely one of the gemstones of this article. a few fascinating purposes of the calculus are provided together with form optimization, boundary perturbation of boundary worth difficulties and dynamic fluid movie equations constructed by means of the writer in recent times. moreover, the relocating surfaces framework is used to provide new derivations of classical effects reminiscent of the geodesic equation and the prestigious Gauss-Bonnet theorem.
