This text investigates the application and derivation of special functions as they pertain to problems in theoretical physics and physical chemistry. Ian Bruce Sneddon, a noted mathematician, provides a rigorous mathematical framework for understanding functions such as the gamma, beta, and hypergeometric functions. The book focuses on the utility of these functions in solving differential equations that arise in quantum mechanics and molecular dynamics.

Experts recognize this work as a concise and focused introduction to the mathematical tools required for graduate-level physics and chemistry. Readers frequently note the academic density of the prose, which assumes a solid foundation in calculus and differential equations.
