Weighted Geometric Means of Positive Operators [PDF]

open access: yesKyungpook mathematical journal, 2010
A weighted version of the geometric mean of k () positive invertible operators is given. For operators and for nonnegative numbers such that , we define weighted geometric means of two types, the first type by a direct construction through symmetrization procedure, and the second type by an indirect construction through the non-weighted (or uniformly ...

Uncertain Bonferroni Mean Operators [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2010
The Bonferroni mean is a traditional mean type aggregation operator bounded by the max and min operators, which is suitable to aggregate the crisp data. In this paper, we consider situations where the input data are interval numbers.

Taylor’s Formula for Generalized Weighted Fractional Derivatives with Nonsingular Kernels

open access: yesAxioms, 2022
We prove a new Taylor’s theorem for generalized weighted fractional calculus with nonsingular kernels. The proof is based on the establishment of new relations for nth-weighted generalized fractional integrals and derivatives. As an application, new mean

A Decision-Making Approach for the Evaluation of Information Security Management under Complex Intuitionistic Fuzzy Set Environment

open access: yesJournal of Mathematics, 2022
Since intuitionistic fuzzy set only deals with uncertainty but not periodicity, therefore to overcome, this situation complex intuitionistic fuzzy set is a better tool that deals with both uncertainty and periodicity.

Dynamic Multi-Attribute Decision-Making Based on Interval-Valued Picture Fuzzy Geometric Heronian Mean Operators

open access: yesIEEE Access, 2022
For the dynamic multi-attribute decision-making problem, the decision information is usually given in the form of the interval-valued picture fuzzy number (IVPFN), and the attributes are also usually related to each other, a decision method based on the ...

ON WEIGHTED INEQUALITIES WITH GEOMETRIC MEAN OPERATOR [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2008
AbstractWe give a characterization of pairs of weights for the validity of weighted inequalities involving certain generalized geometric mean operators generated by some Volterra integral operators, which include the Hardy averaging operator and the Riemann–Liouville integral operators. The estimations of the constants are also discussed.
