This is a book on the numerical approximation of partial differential equations. A theoretical analysis, description of algorithms and a discussion of applications are given. Many kinds of problems are addressed: linear and nonlinear, steady and time-dependent, having smooth or non-smooth solutions.

Part I is devoted to different discretizations of partial differential equations. In particular, the finite element method (conforming, non- conforming, mixed, hybrid) and the spectral method (Legendre and Chebyshev expansion) are investigated.

For unsteady problems the finite difference and fractional-step schemes for marching in time are studied. Finite differences and finite volume methods are extensively considered in Parts II and III in the framework of convection-diffusion problems and hyperbolic equations. For the solution of the resulting algebraic systems direct and iterative solvers (with preconditioning) are presented. A short account is also given to multigrid and domain decomposition methods.

The authors consider all classical equations of mathematical physics: elliptic, parabolic and hyperbolic equations. Furthermore, the advection- diffusion and Navier-Stokes equations for viscous incompressible flows are investigated. The general equations of fluid dynamics are derived.
