A lower bound for the equilateral number of normed spaces
Swanepoel, Konrad J.; Villa Caro, Rafael (American Mathematical Society, 2008)We show that if the Banach-Mazur distance between an n-dimensional normed space X and ℓ n∞ is at most 3/2, then there exist ...

An application of mixture distributions in modelization of length of hospital stay
Atienza Martínez, María Nieves; García Heras, Joaquín; Muñoz Pichardo, Juan Manuel; Villa Caro, Rafael (Wiley, 2008)Length of hospital stay (LOS) is an important indicator of the hospital activity and management of health care. The ...

Brunn-Minkowski and Zhang inequalities for convolution bodies
Alonso Gutiérrez, David; Jiménez Gómez, Carlos Hugo; Villa Caro, Rafael (Elsevier, 2013-05-01)A quantitative version of Minkowski sum, extending the definition of θ-convolution of convex bodies, is studied to obtain ...

Concentration of the distance in finite dimensional normed spaces
Arias de Reyna Martínez, Juan; Ball, Keith; Villa Caro, Rafael (University College London, Faculty of Mathematical and Physical Sciences, Department of Mathematics, 1998-12)We prove that in every finite dimensional normed space, for “most” pairs (x, y) of points in the unit ball, ∥x − y∥ is ...

John's ellipsoid and the integral ratio of a log-concave function
Alonso Gutiérrez, David; González Merino, Bernardo; Jiménez Gómez, Carlos Hugo; Villa Caro, Rafael (Springer, 2018-04)We extend the notion of John’s ellipsoid to the setting of integrable log-concave functions. This will allow us to define ...

Maximal equilateral sets
Swanepoel, Konrad J.; Villa Caro, Rafael (Springer, 2013-09)A subset of a normed space X is called equilateral if the distance between any two points is the same. Let m(X) be the ...

On the consistency of MLE in finite mixture models of exponential families
Atienza Martínez, María Nieves; García Heras, Joaquín; Muñoz Pichardo, Juan Manuel; Villa Caro, Rafael (Elsevier, 2007)Finite mixtures of densities from an exponential family are frequently used in the statistical analysis of data. Modelling ...

Rogers-Shephard inequality for log-concave functions
Alonso Gutiérrez, David; González Merino, Bernardo; JIménez Gömez, Carlos Hugo; Villa Caro, Rafael (Elsevier, 2016-12-01)In this paper we prove different functional inequalities extending the classical Rogers-Shephard inequalities for convex ...
