* Connections between the mathematics and physical interpretations of PDEs
* Numerous exercises, many with solutions provided
* Experimental, computer-based exercises designed to develop lines of inquiry.
The treatment of second order PDEs focuses on well-posed problems, properties and behavior of solutions, existence and uniqueness of solutions, and techniques for writing representations of solutions. Techniques include the use of characteristics, Fourier methods, and, for the Dirichlet problem, Green's function and conformal mappings. Also included are the Kirchhoff/Poisson solution of the wave equation, Huygens's principle, and Lebesgue's example of a Dirichlet problem with no solution.
- Emphasizes the structural aspects of partiallydifferential equations, using the geometry of characteristicsas a starting point
- · Introduces theory at an introductory level,backed by excellent explanations of techniques and numerous practicalexamples
- The exercises serve two purposes: Some are computational,ranging from routine to challenging with answers to many of thequestions included in the back of the book. Other exercises provideadditional information regarding partial differential equations. For these, the title includes hints for the development of aproof or derivation.
- Problems are based on physical phenomena suchas the effects of density on the vibrations of a guitar string. Sections of the problems invite graphic representation and computationalpackages as MAPLE® or MATHEMATICA® can be used to enhancethese exercises
- · Provides students with a sound foundationin partial differential equations· Fills a niche in the world of mathematicsby serving as a bridge to higher concepts· Does not assume the reader possesses knowledgeof Fourier Analysis and incorporates descriptions of the techniqueinto its text
