Version 1

A handbook of the most important techniques used in solving ordinary and partial differential equations. In this edition the section on numerical methods has been expanded and many new sections are included on topics such as finite difference formulae, grid generation, lattice gases, multigrid methods, parallel computers and software availability. New and improved sections on chaos, existence, uniqueness and stability theorems, inverse problems, normal forms and exact partial differential equations have also been included, with computer programmes where possible.
