The book describes and illustrates how to apply effective analytical methods to obtain exact solutions to nonlinear differential equations of mathematical physics and other partial differential equations.
Exact Methods for Nonlinear PDEs is devoted to the description and practical application of effective analytical methods for finding exact solutions to nonlinear partial differential equations. It covers methods of generalized separation of variables, methods of functional separation of variables, the classical method of symmetry reductions, the direct method of symmetry reductions, the method of weak symmetry reductions, and the method of differential constraints. Furthermore, the book describes several simple methods for finding exact solutions to nonlinear PDEs that do not require specialized knowledge and minimize intermediate calculations. For the first time, the use of non-rigorous reasoning based on heuristic principles such as "from simple to complex" and "structural analogy of solutions" for deriving exact solutions to nonlinear PDEs is discussed. Each section includes numerous examples and exercises to help readers build practical skills in applying the methods. The presentation of the material is illustrated using equations of mass and heat transfer, hydrodynamics, wave theory, nonlinear optics, and other nonlinear equations of mathematical physics.
The key points that distinguish this book from others in the field include:
Many methods are presented in a simpler and more visual format.
The material is accessible to a broader range of readers than usual, including those with minimal training and no specialized mathematical education.
Several simple methods for constructing exact solutions to nonlinear PDEs and delay PDEs, which minimize intermediate calculations are described.
It emphasizes and details the practical use of non-rigorous reasoning to derive exact solutions for nonlinear PDEs.
The text is intended for a diverse audience including researchers, university professors, engineers, postgraduates, and students specializing in applied mathematics, theoretical physics, and engineering sciences.

Additional Delivery Information (and some really important bits):
UK Delivery
Orders for delivery in the UK are normally despatched by Royal Mail, using the RM 48 Tracked Service with most orders delivered to you within a few days of placing your order with us. For larger parcels, Courier and Signed For delivery services may be used. Signed Books are shipped in our specially made book mailing cartons, with the books themselves wrapped in paper to protect them. Sometimes we may ship your order in several parts, particularly if you have 'Pre-Order' titles in your order or titles which are held in stock with our publishing partners.
The Really Important Bit: Because we use tracked, courier and signed for delivery services, please use an address at which your parcel can be received during the normal working day, for example, you may want to have your order delivered to your work address if you're not at home during the day.
First Item @ £3.75 (sometimes a shipping supplement may be added for particularly heavy books or specific postcodes*)
2 Items & over @ £5.00 in total
Another Really Important Bit: There are a number of Postcodes in the UK for which we will need to charge a shipping supplement, this will be calculated once we know the size and weight of the shipment. For these orders we will contact customers to agree a suitable and economic method of shipping. There may also be additional time required for delivery to some areas of the United Kingdom. Where possible, we will ship book orders (under 2kg) by Royal Mail to all UK postcodes. Large multiple book orders and books over 2kg are often shipped via APC Overnight or similar, regardless of Postcode.
Overseas Delivery
Shipments to EU countries:
First Item @ £15.00 (sometimes a shipping supplement will be added for particularly heavy books)
2 Items & over @ £30.00 in total
A really, really important Brexit bit: From 1st January 2021 shipments to EU addresses may incur additional costs which could be requested by Fed Ex at the time of delivery. These costs may vary from country to country and are not within our control and will be in addition to the costs paid to us for your delivery.
