Sharp inequalities for logarithmic coefficients and their applications

نویسندگان

چکیده

I. M. Milin proposed, in his 1971 paper, a system of inequalities for the logarithmic coefficients normalized univalent functions on unit disk complex plane. This is known as conjecture and implies Robertson which turn Bieberbach conjecture. In 1984, Louis de Branges settled long-standing by showing Recently, O. Roth proved an interesting sharp inequality based proof Branges. this following Roth's ideas, we will show more general with convex sequences weight functions. By specializing sequence, can obtain abundant number coefficients, some are provided Appendix. We also consider help linear ODE non-convex where partly assisted computer. Also, apply those to improve previously results.

Sharp Logarithmic Sobolev Inequalities on Gradient Solitons and Applications

We show that gradient shrinking, expanding or steady Ricci solitons have potentials leading to suitable reference probability measures on the manifold. For shrinking solitons, as well as expanding soltions with nonnegative Ricci curvature, these reference measures satisfy sharp logarithmic Sobolev inequalities with lower bounds characterized by the geometry of the manifold. The geometric invari...

Sharp Inequalities Involving Neuman–sándor and Logarithmic Means

Sharp bounds for the Neuman-Sándor mean and for the logarithmic mean are established. The bounding quantities are the one-parameter bivariate means called the p-means. In this paper best values of the parameters of the bounding means are obtained. Mathematics subject classification (2010): 26E60, 26D07, 26D20.

Sharp inequalities for tangent function with applications

In the article, we present new bounds for the function [Formula: see text] on the interval [Formula: see text] and find sharp estimations for the Sine integral and the Catalan constant based on a new monotonicity criterion for the quotient of power series, which refine the Redheffer and Becker-Stark type inequalities for tangent function.

Optimal inequalities for the power, harmonic and logarithmic means

For all $a,b>0$, the following two optimal inequalities are presented: $H^{alpha}(a,b)L^{1-alpha}(a,b)geq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain[frac{1}{4},1)$, and $ H^{alpha}(a,b)L^{1-alpha}(a,b)leq M_{frac{1-4alpha}{3}}(a,b)$ for $alphain(0,frac{3sqrt{5}-5}{40}]$. Here, $H(a,b)$, $L(a,b)$, and $M_p(a,b)$ denote the harmonic, logarithmic, and power means of order $p$ of two positive numbers...
