Amdeberhan, Tewodros (ed.) et al., Gems in experimental mathematics. AMS special session on experimental mathematics, Washington, DC, January 5, 2009. Providence, RI: American Mathematical Society (AMS) (ISBN 978-0-8218-4869-2/pbk). Contemporary Mathematics 517, 381-413 (2010).
Summary: Motivated by the relationship of classical modular functions and Picard-Fuchs linear differential equations of order 2 and 3, we present an analogous concept for equations of order 4 and 5.
