WebOn Some Inequalities for the Gamma Function 265 4 On Some Mean Value Inequalities W. Gautschi [2] proved the following conjecture of V.R. Uppuluri [18] 1 2 (x) + 1 x (x) 1 x (4.1) which, because of the arithmetic-geometric mean inequality, implies that (x) 1 x 1: (4.2) An alternative proof of (4.2) was given by Kairies [6]. The lower bound in ... WebAug 1, 2001 · This result is based on monotonicity properties of some functions connected with ψ=Γ′/Γ and it is stronger than the Gautschi inequality . A natural attempt at generalizing to more variables would be n ∑ k=1 n 1/Γ(x k) 1 x 2 …x n) 1/n, which however is false (see for example the case n=2, x 1 =1, x 2 large). Gautschi showed that the ...

WebWhat Gautschi actually proves in his paper is the more general inequality. where ψ ( n) is the digamma function. via l'Hôpital. Then we have. we have φ ( 0) = ψ ( n) − log n < 0, φ ( 1) = 0, and φ ′ ( s) = ( 1 − s) ψ ( 1) ( n + s) (where ψ ( 1) ( n) is the trigamma function). WebGautschi has over 98 years of experience in the design of melting and holding furnaces for the aluminum industry.Gautschi is known for robust construction, modern and innovative technologies and service. It is represented all over the world by more than 500 furnaces, ranging from 500 kg to 140 mt liquid metal capacity.
