: This book is pedagogically organized into nine chapters, with specific focus on linear and nonlinear equations and their real-world applications.
An integral equation is any equation in which the unknown function appears under an integral sign. A classic example is the Fredholm integral equation of the second kind:

Integral equations play a foundational role in modern mathematics, physics, and engineering. Unlike differential equations, which relate a function to its derivatives at specific points, integral equations involve an unknown function under an integral sign. This global, rather than local, formulation makes them incredibly powerful for modeling physical phenomena like heat transfer, quantum mechanics, and fluid dynamics.
The books treat methods as algorithms, making them easy to program into computational software like MATLAB, Mathematica, or Maple.
