This textbook is distinguished from other texts on the subject by the depth of the presentation & the discussion of the calculus of moving surfaces which is an extension of tensor calculus to deforming manifolds Designed for advanced undergraduate & graduate students this text invites its audience to take a fresh look at previously learned material through the prism of tensor calculus Once the framework is mastered the student is introduced to new material which
Includes:: differential geometry on manifolds shape optimization boundary perturbation & dynamic fluid film equations The language of tensors originally championed by Einstein is as fundamental as the languages of calculus & linear algebra & is one that every technical scientist ought to speak The tensor technique invented at the turn of the 20th century is now considered classical Yet as the author shows it remains remarkably vital & relevant The author's skilled lecturing capabilities are evident by the inclusion of insightful examples & a plethora of exercises A great deal of material is devoted to the geometric fundamentals the mechanics of change of variables the proper use of the tensor notation & the discussion of the interplay between algebra & geometry The early chapters have many words & few equations The definition of a tensor comes only in Chapter 6
- when the reader is ready for it While this text maintains a consistent level of rigor it takes great care to avoid formalizing the subject The last part of the textbook is devoted to the Calculus of Moving Surfaces It is the first textbook exposition of this important technique & is one of the gems of this text A number of exciting applications of the calculus are presented including shape optimization boundary perturbation of boundary value problems & dynamic fluid film equations developed by the author in recent years Furthermore the moving surfaces framework is used to offer new derivations of classical results such as the geodesic equation & the celebrated Gauss-Bonnet theorem
