The difference between the metric dimension and the determining number of a graph
(2014)
We study the maximum value of the difference between the metric dimension and the determining number of a graph as a function of its order. We develop a technique that uses functions related to locating-dominating sets to ...

Scutoids are a geometrical solution to three-dimensional packing of epithelia
(Nature Publishing Group, 2018)
As animals develop, tissue bending contributes to shape the organs into complex three-dimensional structures. However, the architecture and packing of curved epithelia remains largely unknown. Here we show by means of ...

Transforming triangulations on non planar-surfaces
(2003)
We consider whether any two triangulations of a polygon or a point set on a non-planar surface with a given metric can be transformed into each other by a sequence of edge flips. The answer is negative in general with some ...

Shortcut sets for the locus of plane Euclidean networks
(Elsevier, 2018)
We study the problem of augmenting the locus N of a plane Euclidean network N by in- serting iteratively a finite set of segments, called shortcut set , while reducing the diameterof the locus of the resulting network. ...

Hamiltonian triangular refinements and space-filling curves
(Elsevier, 2019)
We have introduced here the concept of Hamiltonian triangular refinement. For any Hamiltonian triangulation it is shown that there is a refinement which is also a Hamiltonian triangulation and the corresponding Hamiltonian ...
