Part I deals withhp-adaptive finite elements in 1D. Chap. 1 defines the 1D model elliptic problem and basic notation. Chap. 2 recalls the Galerkin method. The 1Dhpfinite element method is explained in Chap. 3, including the ingredients required to create a finite element approximation with variable element size and polynomial degree. The one-dimensional hp-code which comes with the book is explained in Chap. 4, where fundamentals like data structure, graphics, and element routines are discussed. Mesh refinements, both in h and p are presented in Chap. 5, where the concepts of h-refinement extension operators and projection-based interpolation are introduced. Next, the fully automatic hp-adaptive procedure for the 1D problem is presented in Chap. 6. Part I ends with Chap. 7, discussing wave propagation problems and extending the hp-adaptive procedure to the solution of a vibrating elastic bar.Part II is devoted to two-dimensional elliptic problems. The order of presentation is similar to that in Part I. After the formulation of a 2D elliptic boundary value problem in Chap. 8, Sobolev spaces in the multidimensional context are discussed in Chap. 9. Chap. 10 presents the fundamentals of hp finite elements and in Chap. 11 the 2D hp code which comes with the book is explained. Since the geometric description of high order elements is crucial, Chap. 12 is devoted to geometric modelling and mesh generation. The hp-FEM on h-refined meshes and automatic hp-adaptivity in
