{"product_id":"9780387974910","title":"Algebraic Methods in Nonlinear Perturbation Theory","description":"Of interest to everybody working on perturbation theory in differential equations, this book requires only a standard mathematical background in engineering and does not require reference to the special literature. Topics covered include: matrix perturbation theory; systems of ordinary differential equations with small parameters; reconstruction and equations in partial derivatives. While boundary problems are not discussed, the book is clearly illustrated by numerous examples.","brand":"V.N. Bogaevski, A.
