Nonparametric estimation of the multivariate Spearman's footrule: a further discussion
Ana Pérez, Mercedes Prieto-Alaiz, Fernando Chamizo +2
In this paper, we propose two new estimators of the multivariate rank correlation coefficient Spearman's footrule which are based on two general estimators for Average Orthant Depe…
On sets with missing differences in compact abelian groups
Pablo Candela, Fernando Chamizo, Antonio Córdoba
A much-studied problem posed by Motzkin asks to determine, given a finite set of integers, the so-called Motzkin density for , i.e., the supremum of upper densities of sets…
Regular Polygonal Vortex Filament Evolution and Exponential Sums
Fernando Chamizo, Francisco de la Hoz
In this paper, we give a rigorous proof for the expression of the angle between adjacent sides in the skew polygons appearing at rational times in the evolution of regular polygons…
Correlation and lower bounds of arithmetic expressions
Fernando Chamizo
We explore the use of correlation with simple functions to get lower bounds for arithmetic quantities. In particular, we apply this idea to the power moments of the error term when…
About the quantum Talbot effect on the sphere
Fernando Chamizo, Osvaldo Santillan
The Schrödinger equation on a circle with an initially localized profile of the wave function is known to give rise to revivals or replications, where the probability density of th…
Current induction and macroscopic forces for superconducting strings
Fernando Chamizo, Osvaldo Santillán
Vortons are extended superconducting rings, which hypothetically may play a role in cosmology and even may have significance in connection with cosmic rays of high energy. Some of…
