چکیده
In this paper, we generalize and refine some Berezin number inequalities for Hilbert space operators. Namely, the Hermite-Hadamard inequality other recent results by using concept of superquadraticity convexity. Then extend these number. Among inequalities, it is shown that if S, T ? L(H(?)) such ber(T) ber(|S|) f a nonnegative superquadratic function, then (ber (T)) ber(f (|S|)) ?ber (f (||S| ber (T)|)).

Inequalities for Averages of Convex and Superquadratic Functions
We consider the averages An(f) = 1/(n − 1) ∑n−1 r=1 f(r/n) and Bn(f) = 1/(n + 1) ∑n r=0 f(r/n). If f is convex, then An(f) increases with n and Bn(f) decreases. For the class of functions called superquadratic, a lower bound is given for the successive differences in these sequences, in the form of a convex combination of functional values, in all cases at least f(1/3n). Generalizations are for...
متن کاملRefined Convex Sobolev Inequalities
This paper is devoted to refinements of convex Sobolev inequalities in the case of power law relative entropies: a nonlinear entropy–entropy production relation improves the known inequalities of this type. The corresponding generalized Poincaré type inequalities with weights are derived. Optimal constants are compared to the usual Poincaré constant.
متن کامل(m1,m2)-AG-Convex Functions and Some New Inequalities
In this manuscript, we introduce concepts of (m1,m2)-logarithmically convex (AG-convex) functions and establish some Hermite-Hadamard type inequalities of these classes of functions.
متن کاملHermite-Hadamard inequalities for $mathbb{B}$-convex and $mathbb{B}^{-1}$-convex functions
Hermite-Hadamard inequality is one of the fundamental applications of convex functions in Theory of Inequality. In this paper, Hermite-Hadamard inequalities for $mathbb{B}$-convex and $mathbb{B}^{-1}$-convex functions are proven.
متن کاملInequalities of Ando's Type for $n$-convex Functions
By utilizing different scalar equalities obtained via Hermite's interpolating polynomial, we will obtain lower and upper bounds for the difference in Ando's inequality and in the Edmundson-Lah-Ribariv c inequality for solidarities that hold for a class of $n$-convex functions. As an application, main results are applied to some operator means and relative operator entropy.
