First-order linear differential equations with involutive delay and hypergeometric functions
We present an alternative approach to functions satisfying second-order linear ordinary differential equations. It turns out that many of them satisfy a first-order ordinary differential equation with an involution. The involution acts on the argument as well as on parameters. Basic examples involve the hypergeometric functions and their descendants.
