Asmar Department of Mathematics University of Missouri Columbia, Missouri Errata The following mistakes appeared in the first printing of the second edition. Corrections in the text and figures p.

## If You're a Student

Corrections to Answers of Odd Exercises Section 7. Section 7.

Any suggestion or correction would be greatly appreciated. The solution is very similar to Exercise 5. We follow the method of characteristic curves.

A similar argument shows that v is a solution of the one dimensional wave equation. As the hint suggests, we consider two separate problems: The problem in Exercise 5 and the one in Exercise 7. Examples of partial differential equations: Solutions of a homogeneous, linear PDE form a vector space; inhomogeneous equations: How a Gaussian function as initial condition evolves in each of the examples. General solution of the transport equation in 2 variables.

Method of characteristics to solve here: Wave equation on the interval [0,L], initial conditions, boundary conditions, normal modes, more complicated solution by superposition i. This lecture corresponds roughly to Asmar, Chapter 1 Sept 7: Motivating Fourier series for equations with constant coefficients: Piecewise continuous and piecewise smooth functions, periodic functions, the Fourier system of trigonometric functions and their orthogonality properties.

Fourier expansions of piecewise smooth functions: The Gibbs phenomenon; more can be found at http: This lecture corresponds roughly to Asmar, Chapter 2, Sections 1 and 2 Further references: Good elementary, though rather comprehensive accounts of the classical theory of Fourier series are Edwards, "Fourier series 1,2", Springer and Zygmund, "Trigonometric Series", Cambridge University Press.

The former contains, in particular, a classical example due to Fejer of a continuous function whose Fourier series diverges in a point. Sept We continue our discussion of Fourier series, also for periodic functions of arbitrary period. Topics include a short discussion of the proof of the pointwise convergence theorem, the Fourier series of even and odd functions, sine and cosine series.

Then expansions of real and complex functions in series of complex trigonometric functions are discussed. This roughly corresponds to Asmar, sections 2.

## Asmar - Partial Differential Equations

We further discuss the approximation properties of Fourier series: Then we recall basic properties of linear partial differential equations. The material roughly correponds to Asmar, sections 2.

We start with the classification of second-order linear PDE into elliptic, parabolic and hyperbolic problems. Then the solution of the one-dimensional wave equation for given initial conditions is discussed, combining separation of variables with Fourier series. The topics correspond to Asmar, sections 3. However, the solutions described in the examples in this book are "generalized solutions". We provide sufficient conditions for having "classical" i. Supplementing notes by Gerd Grubb can be found here: We recall the basic ideas of the Fourier-theoretic solution and its theoretical analysis. It allows the discussion of domains of dependence and the influence of inital singularities. The new material corresponds to section 3. First we finished the discussion of d'Alembert's solution for the wave equation and use characteristic parallelograms to find simple expressions for the solution in subsets of the t,x -space.

We then continued with the one-dimensional heat equation with various boundary conditions, again solved using separation of variables and Fourier series. We discussed the two-dimensional heat and wave equations. Like for the wave equation, we also briefly addressed the convergence of the series solution in the one-dimensional case, which turned out to be simpler than for the wave equation. The material corresponds to the last bits of section 3. You can find an informative treatment of convergence issues in Gerd Grubb's notes http:Examples of partial differential equations: Any suggestion or correction would be greatly appreciated.
