On 4-connected geometric graphs
(2013)Given a set S of n points in the plane, in this paper we give a necessary and sometimes sufficient condition to build a 4-connected non-crossing geometric graph on S.

On fencing problems
(2004)Fencing problems deal with the bisection of a convex body in a way that some geometric measures are optimized. We study ...

On geodesic and monophonic convexity
(2004)In this paper we deal with two types of graph convexities, which are the most natural path convexities in a graph and which ...

On geometric properties of enumerations of axis-parallel rectangles
(2004)We show that for any set of non-overlapping axis-parallel rectangles in the plane, there exists a sloping enumeration, ...

On making a graph crossing-critical
(2013)A graph is crossing-critical if its crossing number decreases when we remove any of its edges. Recently it was proved that ...

On rectangular cartograms
(2004)A rectangular cartogram is a type of map where every region is a rectangle. The size of the rectangles is chosen such that ...

On relative isodiametric inequalities
(2004)We consider subdivisions of convex bodies G in two subsets E and G\E. We obtain several inequalities comparing the relative ...

On spectral structure of bounded linear operators on reflexive Banach spaces
(Editorial Universidad de Sevilla, 2005)A descriptive characterization of point, continuous, and residual spectra of operators acting on a separable Hilbert space is obtained. The possible point spectra of bounded linear operators acting on lp, 1 < p < ∞ are characterized.

On the barrier-resilience of arrangements of ray-sensors
(2013)Given an arrangement A of n sensors and two points s and t in the plane, the barrier resilience of A with respect to s and ...

On the enumeration of permutominoes
(2013)Although the exact counting and enumeration of polyominoes remain challenging open problems, several positive results were ...

On the growth of Hardy and Bergman norms of functions in the Dirichlet space
(Editorial Universidad de Sevilla, 2005)We review the Chang-Marshall inequality of Moser-Trudinger type for the Dirichlet space. We then use a weaker version of ...

On the intersection of the classes of doubly diagonally dominant matrices and S-strictly diagonally dominant matrices
(2007-09)We denote by H0 the subclass of H-matrices consisting of all the matrices that lay simultaneously on the classes of doubly ...

On the mixed finite element approximation of wave problems. Application to shallow water flows
(2007-09)The purpose of this paper is to present a finite element approximation of the scalar hyperbolic wave equation written in ...

On the nonexistence of k-reptile simplices in R3 and R4
(2013)A d-dimensional simplex S is called a k-reptile (or a k-reptile simplex) if it can be tiled without overlaps by k simplices ...

On the number of pseudo-triangulations of certain point sets
(2004)We compute the exact number of pseudo-triangulations for two prominent point sets, namely the so-called double circle and ...

On three parameters of invisibility graphs
(2013)The invisibility graph I(X) of a set X ⊆ Rd is a (possibly infinite) graph whose vertices are the points of X and two ...
