Norm inequalities related to Heinz and Heron operator means
A. G. Ghazanfari
In this article we present some new comparisons between the Heinz and Heron operator means, which improve some recent results known from the literature. We derive some refinements…
Complementary inequalities to Davis-Choi-Jensen's inequality and operator power means
A. G. Ghazanfari
Let be an operator convex function on , and be a unital positive linear maps on . we give a complementary inequality to Davis-Choi-Jensen's inequality as…
Refined Heinz operator inequalities and norm inequalities
Amir Ghasem Ghazanfari
In this article we study the Heinz and Hermite-Hadamard inequalities. We derive the whole series of refinements of these inequalities involving unitarily invariant norms, which imp…
Some Gruss type inequalities for Frechet differentiable mappings
Teimouri Azadbakht, Amir Ghasem Ghazanfari
Let X be a Hilbert C^*-module on C^*-algebra A and p in A. We denote by Dp(A;X) the set of all continuous functions f on A, which are Frechet differentiable on a open neighborhood…
Some new inequalities involving Heinz operator means
A. G. Ghazanfari, S. Malekinejad, S. Talebi
We give some new refinements of Heinz inequality and an improvement of the reverse Young's inequality for scalars and we use them to establish new inequalities for operators and th…
On approximate ternary m-derivations and -homomorphisms
A. G. Ghazanfari, Z. Alizadeh
In this paper we introduce ternary modules over ternary algebras and using fixed point methods, we prove the stability and super-stability of ternary additive, quadratic, cubic and…
