Lion and man in non-metric spaces
(Springer, 2018-12)
A lion and a man move continuously in a space X. The aim of the lion is to capture his prey while the man wants to escape forever. Which of them has a strategy? This question has been studied for different metric domains. ...
An empirical evaluation of intrinsic dimension estimators
(Elsevier, 2017)
We study the practical behavior of different algorithms and methods that aim to estimate the intrinsic dimension (IDim) in metric spaces. Some of them were specifically developed to evaluate the complexity of searching in ...
Examples of homogeneous manifolds with uniformly bounded metric projection
(Unión Matemática Argentina, 2012-11)
Let M be a finite von Neumann algebra with a faithful normal trace τ. Denote by Lp(M)sh the skew-Hermitian part of the non-commutative Lp space associated with (M, τ). Let 1 < p < ∞, z ∈ Lp(M)sh and S be a real closed ...
An efficient algorithm for approximated self-similarity joins in metric spaces
(Elsevier, 2020)
Similarity join is a key operation in metric databases. It retrieves all pairs of elements that are similar. Solving such a problem usually requires comparing every pair of objects of the datasets, even when indexing and ...
On fixed points and convergence results of sequences generated by uniformly convergent and point‑wisely convergent sequences of operators in Menger probabilistic metric spaces
In the framework of complete probabilistic Menger metric spaces, this paper investigates
some relevant properties of convergence of sequences built through sequences
of operators which are either uniformly convergent to ...
Lines in bipartite graphs and in 2-metric spaces
(Wiley, 2020)
The line generated by two distinct points, x and y, in a finite metric space M=(V,d), is the set of points given by {z is an element of V:d(x,y)=|d(x,z)+d(z,y)|ord(x,y)=|d(x,z)-d(z,y)|}. It is denoted by xy over bar M. A ...
Symmetry groups of Rosenbloom-Tsfasman spaces

Adapting metric indexes for searching in multi-metric spaces
(KLUWER ACADEMIC PUBLISHERS, 2012)
Metric-Space Approach for Distinguishing Quantum Phase Transitions in Spin-Imbalanced Systems
(Springer, 2018-10-01)
Metric spaces are characterized by distances between pairs of elements. Systems that are physically similar are expected to present smaller distances (between their densities, wave functions, and potentials) than systems ...
