Sharp Integral Inequalities for Trigonometric Polynomials
Sharp inequalities for linear operators in the set of trigonometric polyno-mials with respect to integral functionals Ê 2π 0 ϕ(|f (x)|) dx over the class of all functions ϕ defined, nonnegative, and nondecreasing on the semi-axis [0, ∞) are discussed. 1.1. Let P be the real number field R or the complex number field C depending on the situation. Let C 2π = C 2π (P) be the space of continuous 2π...

* Correspondence: chjzhao@163. com Department of Mathematics, China Jiliang University, Hangzhou 310018, P. R. China Full list of author information is available at the end of the article Abstract The main purpose of the present article is to establish some new sharp integral inequalities in 2n independent variables. Our results in special cases yield some of the recent results on Pachpatter, A...
متن کاملOn the L2 Inequalities Involving Trigonometric Polynomials and Their Derivatives
In this note we study the upper bound of the integral f {tW(x))2w(x)dx Jo where t(x) is a trigonometric polynomial with real coefficients such that \\t\\ao < 1 and w(x) is a nonnegative function defined on [0, n]. When w{x) = sin; x , where j is a positive integer, we obtain the exact upper bound for the above integral.
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 کاملHilbert-pachpatte Type Integral Inequalities for Fractional Derivatives∗
In this paper we continue our investigation of multivariable integral inequalities of the type considered by Hilbert and recently by Pachpatte by focusing on fractional derivatives. Our results apply to integrable not necessarily continuous functions, and we are able to relax the original conditions to admit negative exponents in the weight functions. Mathematics Subject Classification: 26A33, ...
