Apery Limits of Differential Equations of Order 4 and 5
(2008) Workshop on Modular Forms and String Duality In MODULAR FORMS AND STRING DUALITY 54. p.105123 Abstract
 The concept of Apery limit for second and third order differential equations is extended to fourth and fifth order equations, mainly of CalabiYau type. For those equations obtained from Hadamard products of second and third order equations we can prove that the limits are determined in terms of the factors by a certain formula. Otherwise the limits are found by using PSLQ in Maple and are only conjectural. All identified limits are rational linear combinations of the following numbers: pi(2) Catalan's constant G, Sigma(infinity)(n=1) (n/3)/n(2); pi(3), pi(3), zeta(3), pi(3)root 3, pi(4).
