Sharp Inequalities for Polygamma Functions
where μ is a nonnegative measure on [0,∞) such that the integral (2) converges for all x > 0. This means that a function f(x) is completely monotonic on (0,∞) if and only if it is a Laplace transform of the measure μ. The completely monotonic functions have applications in different branches of mathematical sciences. For example, they play some role in combinatorics, numerical and asymptotic an...
متن کاملSharp Inequalities for Trigonometric and Hyperbolic Functions
We establish several sharp inequalities for trigonometric and hyperbolic functions. Our results sharpen some known inequalities. Mathematics subject classification (2010): 26D05, 26D07.
متن کاملSharp integral inequalities for harmonic functions
Motivated by Carleman’s proof of isoperimetric inequality in the plane, we study some sharp integral inequalities for harmonic functions on the upper halfspace. We also derive the regularity for nonnegative solutions of the associated integral system and some Liouville type theorems.
متن کاملSufficient Inequalities for Univalent Functions
In this work, applying Lemma due to Nunokawa et. al. cite{NCKS}, we obtain some sufficient inequalities for some certain subclasses of univalent functions.
متن کاملSome numerical radius inequalities with positive definite functions
Using several examples of positive definite functions, some inequalities for the numerical radius of matrices are investigated. Also, some open problems are stated.
