摘要: This article investigates the algebraic differential independence concerning the Euler Γ-function and the function F in a certain class F which contains Dirichlet L-functions, L-functions in the extended Selberg class, or some periodic functions. We prove that the Euler Γ-function and the function F cannot satisfy any nontrivial algebraic differential equations whose coefficients are meromorphic functions ϕ with ρ(ϕ)<1.

关键词: Gamma function, L-functions, algebraic differential independence, algebraic differential equations
