Boundary Value Problems, 2022 In the paper, we study the oscillatory and spectral properties of a fourth-order differential operator. These properties are established based on the validity of some weighted second-order differential inequality, where the inequality’s weights are the ...

Operator inequalities and normal operators
Banach Journal of Mathematical Analysis, 2012 Over the last years, a lot of work has appeared on operator inequalities. The present authors use some advantages offered by the context of finite-dimensional Hilbert spaces and establish complete characterizations of certain distinguished classes of operators (self-adjoint, unitary reflection, normal) in terms of operator inequalities.

A natural derivative on [0,n] and a binomial Poincar\'e inequality [PDF]
, 2011 We consider probability measures supported on a finite discrete interval $[0,n]$. We introduce a new finitedifference operator $\nabla_n$, defined as a linear combination of left and right finite differences. We show that this operator $\nabla_n$ plays a

An optimal improvement for the Hardy inequality on the hyperbolic space and related manifolds
, 2019 We prove \emph{optimal} improvements of the Hardy inequality on the hyperbolic space. Here, optimal means that the resulting operator is critical in the sense of [J.Funct.Anal. 266 (2014), pp.

A sharp integral inequality for the dyadic maximal operator and a related stability result
, 2019 We prove a sharp integral inequality for the dyadic maximal operator due to which the evaluation of the Bellman function of this operator with respect to two variables is possible, as can be seen in [3].

Operator iteration on the Young inequality
Journal of Inequalities and Applications, 2016 In this paper, we employ iteration on operator version of the famous Young inequality and obtain more arithmetic-geometric mean inequalities and the reverse versions for positive operators.
