Some properties of fuzzy cone symmetric spaces [PDF]

open access: yesJournal of Hyperstructures, 2023
In this work, we give a fuzzy analogy of cone symmetric spaces that we call fuzzy cone symmetric spaces. Since these structurere obtained by omitting the triangle inequality in fuzzy cone metric spaces, there are topological degenerations.

Reverse triangle inequalities for potentials

open access: yesJournal of Approximation Theory, 2009
We study the reverse triangle inequalities for suprema of logarithmic potentials on compact sets of the plane. This research is motivated by the inequalities for products of supremum norms of polynomials. We find sharp additive constants in the inequalities for potentials, and give applications of our results to the generalized polynomials.

Efficient Neighborhood Covering Model Based on Triangle Inequality Checkand Local Strategy [PDF]

open access: yesJisuanji kexue, 2022
Neighborhood covering model is widely used in classification tasks for its simple mechanism and ability to handle complex data.However,the neighborhood covering model has the problem of low efficiency and lack of related research work.To solve this ...

A Triangle Inequality for Cosine Similarity [PDF]

open access: yes, 2021
Similarity search is a fundamental problem for many data analysis techniques. Many efficient search techniques rely on the triangle inequality of metrics, which allows pruning parts of the search space based on transitive bounds on distances. Recently, Cosine similarity has become a popular alternative choice to the standard Euclidean metric, in ...

Some Triangle Inequalities and Generalizations [PDF]

open access: yesCanadian Mathematical Bulletin, 1980
AbstractLet , where ai, s, and x are real, and II denotes the product over cyclic rearrangements of the subscripts. We show that, in five special cases, Dn, s(x)Dn, s(y) is greater than a fixed multiple of Dn, s(x + y).

Controlled Metric Type Spaces and the Related Contraction Principle

open access: yesMathematics, 2018
In this article, we introduce a new extension of b-metric spaces, called controlled metric type spaces, by employing a control function α ( x , y ) of the right-hand side of the b-triangle inequality.

Another Aspect of Triangle Inequality [PDF]

open access: yesISRN Mathematical Analysis, 2011
We introduce the notion of ψ-norm by considering the fact that an absolute normalized norm on C2 corresponds to a continuous convex function ψ on the unit interval [0,1] with some conditions. This is a generalization of the notion of q-norm introduced by Belbachir et al. (2006). Then we show that a ψ-norm is a norm in the usual sense.

Genuine monogamy relations in no-signaling theories—a geometric approach

open access: yesNew Journal of Physics, 2021
Quantum correlations are subject to certain distribution rules represented by so-called monogamy relations. Derivation of monogamy relations for multipartite systems is a non-trivial problem, as the multipartite correlations reveal their behaviors in a ...

A Generalization of the Klamkin Inequality [PDF]

open access: yes, 2009
A generalization of a geometric inequality of Klamkin is established by considering the triples of barycentric coordinates of the points from a set which is included in the plane of the fundamental triangle.
