Ronveaux A. (ed.) Heun's Differential Equations

Oxford University Press, 1995. — 354 p. — ISBN 9781383031034; ISBN 9780198596950.Heun's equation is a second-order differential equation which crops up in a variety of forms in a wide range of problems in applied mathematics. These include integral equations of potential theory, wave propagation, electrostatic oscillation, and Schrodinger's equation. This volume brings together important research work for the first time, providing an important resource for all those interested in this mathematical topic. Both the current theory and the main areas of application are surveyed, and includes contributions from authoritative researchers.Heun's equation
