This well-written book contains the analytical tools, concepts, and viewpoints needed for modern applied mathematics. It treats various practical methods for solving problems such as differential equations, boundary value problems, and integral equations. Pragmatic approaches to difficult equations are presented, including the Galerkin method, the method of iteration, Newton’s method, projection techniques, and homotopy methods.
some errors in proof some theorems are examples some theorems are corollaries, one or two proofs are incorrect (did the secretary mess up the latex?) Some notation is syntatic suggar. No student-solution exists. Plentyfull of examples!
