Further inequalities involving the weighted geometric operator mean and the Heinz operator mean

Linear and Multilinear Algebra, 2021
In this paper, we first investigate some inequalities involving the p-weighted geometric operator mean A ♯ p B = A 1 / 2 ( A − 1 / 2 B A − 1 / 2 ) p A 1 / 2 ,  where p ∈ [ 0 , 1 ] is a real number ...

On additivity of the weighted possibilistic mean operator

2013 IEEE 14th International Symposium on Computational Intelligence and Informatics (CINTI), 2013
In this paper we study the problem of additivity property of the weighted possibilistic mean operator for interactive fuzzy numbers. We will show that the weighted possibilistic mean operator is additive on the set of symmetric fuzzy numbers if their joint possibility distribution is defined by a t-norm. We will also show some results for general joint-

The Spectrum of Weighted Mean Operators

Canadian Mathematical Bulletin, 1987
AbstractRecently J. B. Reade determined the spectrum of C, the Cesaro matrix of order 1, considered as an operator on c0, the space of null sequences. Previously F. P. A. Cass and the author had determined the spectra for a large class of weighted mean operators on c, the space of convergent sequences.

Dynamic Uncertain Linguistic Weighted Geometric Mean Operator

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
With respect to multiple periods multiple attribute decision making problems with uncertain multiplicative linguistic preference relations. Definition and some operational laws of uncertain linguistic variables are introduced, and two new operators called dynamic uncertain linguistic geometric mean (DULGM) operator and dynamic uncertain linguistic ...

Approximation of weighted local mean operators

Applicable Analysis, 2013
Recently, weighted local mean operators are widely used in image processing, compressive sensing and other areas. A weighted local mean operator changes its characteristics depending on a function content within a local area in order to preserve the function features.

Weighted Mean Operators on l_p

Canadian Mathematical Bulletin, 2000
AbstractAbstract. The weightedmean matrix Ma is the triangular matrix {ak/An}, where an > 0 and An := a1 + a2 + … + an. It is proved that, subject to ncan being eventually monotonic for each constant c and to the existence of for 1 < p < ∞ if and only if α < p.

Compact operators on spaces of sequences of weighted means

AIP Conference Proceedings, 2012
We reduce the spaces a 0 r , a c r , a 0 r (Δ) and a c r (Δ) and simplify their dual spaces and the characterisations of matrix transformations on them. We also obtain an estimate and a formula for the Hausdorff measure of noncompactness of some matrix operators on the spaces a 0 r and a c r and the corresponding characterisations of compact matrix ...
