About this title

Synopsis

Explore a rigorous approach to solving complex differential systems with exponential-type solutions.

This book presents a new way to obtain rapidly convergent representations by transforming the Peano–Baker matrizant into a form that reveals the solution as a sum of exponentials with variable coefficients. It links classical ideas like the WKB method to modern matrix techniques, offering a unified view of higher-order systems and turning points.

The text develops the theory step by step, showing how to construct, transform, and connect solutions across regions with and without turning points. It explains when and how the leading terms align with familiar approximations and how to interpret exponential terms as waves or oscillations. The treatment includes asymptotic expansions, scattering matrices, and practical procedures for computing connection data across complex domains.

Learn how to represent solutions as exponential sums with adjustable coefficients, and why this improves convergence.
See how the matrix machinery generalizes the WKB method to higher-order systems and to cases with parameters.
Understand turning points, connection formulas, and how to connect solutions across different regions.
Explore the interpretation of exponential terms as waves and how continuous reflections shape the overall solution.

Ideal for readers of advanced applied mathematics and theoretical physics who want a rigorous, constructive framework for exponential-type solutions.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
