The main functions treated in this chapter are the generalized hypergeometric function Fqp⁡(a1,…,apb1,…,bq;z), the Appell (two-variable hypergeometric) functions F1⁡(α;β,β′;γ;x,y), F2⁡(α;β,β′;γ,γ′;x,y), F3⁡(α,α′;β,β′;γ;x,y), F4⁡(α,β;γ,γ′;x,y), and the Meijer G-function Gp,qm,n⁡(z;a1,…,apb1,…,bq). Alternative notations are Fqp⁡(𝐚𝐛;z), Fqp⁡(a1,…,ap;b1,…,bq;z), and Fqp⁡(𝐚;𝐛;z) for the generalized hypergeometric function, F1⁡(α,β,β′;γ;x,y), F2⁡(α,β,β′;γ,γ′;x,y), F3⁡(α,α′,β,β′;γ;x,y), F4⁡(α,β;γ,γ′;x,y), for the Appell functions, and Gp,qm,n⁡(z;𝐚;𝐛) for the Meijer G-function.
