3D realization of two triangulations of a onvex polygon
(2004)We study the problem of construction of a convex 3-polytope whose (i) shadow boundary has n vertices and (ii) two hulls, ...

Presentation
A certified conflict locator for the incremental maintenance of the Delaunay graph of semi-algebraic sets
(2004)Most of the curves and surfaces encountered in geometric modelling are defined as the set of solutions of a system of ...

A max-flow algorithm for positivity of Littlewood-Richardson coefficients
(2009-11)Littlewood-Richardson coefficients appear as limits of certain families of Kronecker coefficients. They have a wide variety ...

A parametrization for the symbols of a Hankel type operator
(Editorial Universidad de Sevilla, 2005)Hankel operators and their symbols, as generalized by V. Pták and P. Vrbová, are considered. In this more general framework, ...

A quadratic distance bound on sliding between crossing-free spanning trees
(2004)Let S be a set of n points in the plane and let TS be the set of all crossing-free spanning trees of S. We show that any ...
