Interpolating the arithmetic–geometric mean inequality and its operator version

open access: yesLinear Algebra and its Applications, 2006
The paper begins with a nice introduction to means and how inequalities between means often have a matricial unitarily-invariant norm version. While this happens in many known examples, \textit{F. Hiai} and \textit{H. Kosaki} [Indiana Univ. Math. J. 48, No. 3, 899--936 (1999; Zbl 0934.15023)] have shown a counterexample.

Single Valued Bipolar Pentapartitioned Neutrosophic Set and Its Application in MADM Strategy [PDF]

open access: yesNeutrosophic Sets and Systems, 2022
The main objective of this paper is to introduce the notion of single-valued bipolar pentapartitioned neutrosophic set (SVBPNS). We also present some supporting examples and prove some basic properties of SVBPNS.

New q-Rung Orthopair Fuzzy Bonferroni Mean Dombi Operators and Their Application in Multiple Attribute Decision Making

open access: yesIEEE Access, 2020
Some q-rung orthopair fuzzy Bonferroni mean Dombi aggregation operators have been developed based on the Bonferroni mean, Dombi T-norm and T-conorm in q-rung orthopair fuzzy environment.

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 ...

Level set approach for fractional mean curvature flows [PDF]

open access: yes, 2009
This paper is concerned with the study of a geometric flow whose law involves a singular integral operator. This operator is used to define a non-local mean curvature of a set.

On the Geometric Mean Operator

open access: yesJournal of Mathematical Analysis and Applications, 1994
The authors give a characterization of pairs of weights \((u,v)\) such that the geometric mean operator \(Gf(x)= \exp((1/x) \int_ 0^ x \log f(t) dt)\), defined for \(f>0\) almost everywhere on \((0,\infty)\), is bounded from \(L_{p,v} (0,\infty)\) to \(L_{q,u} (0,\infty)\), where \(01\) the good weights for \(G\) coincide with those good for the ...

On the conjecture of the norm Schwarz inequality [PDF]

open access: yes, 2016
For any positive invertible matrix $A$ and any normal matrix $B$ in $M_{n}({\Bbb C})$, we investigate whether the inequality $ ||A\sharp (B^{*}A^{-1}B)||\geq ||B|| $ is true or not, where $\sharp$ denotes the geometric mean and $||\cdot||$ denotes the ...

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.

A Novel Multi-Criteria Group Decision-Making Approach Based on Bonferroni and Heronian Mean Operators under Hesitant 2-Tuple Linguistic Environment

open access: yesMathematics, 2021
Ambiguous and uncertain facts can be handled using a hesitant 2-tuple linguistic set (H2TLS), an important expansion of the 2-tuple linguistic set. The vagueness and uncertainty of data can be grabbed by using aggregation operators.
