Some properties of the gamma and psi functions, with applications
In this paper, some monotoneity and concavity properties of the gamma, beta and psi functions are obtained, from which several asymptotically sharp inequalities follow. Applying these properties, the authors improve some well-known results for the volume Ωn of the unit ball Bn ⊂ Rn, the surface area ωn−1 of the unit sphere Sn−1, and some related constants.
متن کاملMonotonicity of some functions involving the gamma and psi functions
Let L(x) := x − Γ(x+t) Γ(x+s) xs−t+1, where Γ(x) is Euler’s gamma function. We determine conditions for the numbers s, t so that the function Φ(x) := − Γ(x+t) xt−s−1 L′′(x) is strongly completely monotonic on (0, ∞). Through this result we obtain some inequalities involving the ratio of gamma functions and provide some applications in the context of trigonometric sum estimation. We also give se...
متن کاملOn some inequalities for the gamma and psi functions
We present new inequalities for the gamma and psi functions, and we provide new classes of completely monotonic, star-shaped, and superadditive functions which are related to Γ and ψ. 1 Euler’s gamma function Γ(x) = ∫ ∞ 0 e−ttx−1 dt (x > 0) is one of the most important functions in analysis and its applications. The history and the development of this function are described in detail in a paper...

Complete monotonicity properties of some functions involving the psi function are studied and some known results are extended and generalized. Moreover, a necessary and sufficient conditions for some functions to be completely monotonic are presented and proved. Mathematics subject classification (2010): 33B15, 26D15.
