Many physical problems that are usually solved by differential equation
techniques can be solved more effectively by integral equation methods.
This work focuses exclusively on singular integral equations and on the
distributional solutions of these equations. A large number of beautiful
mathematical concepts are required to find such solutions, which in tum,
can be applied to a wide variety of scientific fields - potential
theory, me- chanics, fluid dynamics, scattering of acoustic,
electromagnetic and earth- quake waves, statistics, and population
dynamics, to cite just several. An integral equation is said to be
singular if the kernel is singular within the range of integration, or
if one or both limits of integration are infinite. The singular integral
equations that we have studied extensively in this book are of the
following type. In these equations f (x) is a given function and g(y) is
the unknown function. 1. The Abel equation x x) = l g (y) d 0
