The new reverses of Young type inequalities for numbers, operators and matrices

, 2018
In this note, we give reverses of Young inequality for numbers. Then we establish operator and matrix inequalities corresponding the obtained numerical inequalities. Mathematics subject classification (2010): 47A30, 15A42, 15A60.

On the metrizability of suprametric space

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
The question of metrizability of suprametric space is answered positively. The observed metric coincides with a suprametric in a way that convergence and continuity are preserved between suprametric space and associated metric space along with the ...

Scalar approximants of quadratic operators with applications

, 2018
Among other results, we find the best scalar approximant of a quadratic operator with respect to the numerical radius and the operator norm. We use these results to give estimates for the numerical radii of products and commutators of quadratic operators.

Weak convergence theorems for inertial Krasnoselskii-Mann iterations in the class of enriched nonexpansive operators in Hilbert spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we present some results about the aproximation of fixed points of nonexpansive and enriched nonexpansive operators. In order to approximate the fixed points of enriched nonexpansive mappings, we use the Krasnoselskii-Mann iteration for ...
