On Poncelet's maps
(2010-08-08)
Article
Accés obertGiven two ellipses, one surrounding the other one, Poncelet introduced a map P from the exterior one to itself by using the tangent lines to the interior ellipse. This procedure can be extended to any two smooth, nested ... -
On sets defining few ordinary planes
(2017-09-19)
Article
Accés obertLet S be a set of n points in real three-dimensional space, no three collinear and not all co-planar. We prove that if the number of planes incident with exactly three points of S is less than (Formula presented.) for some ... -
On the relative position of two coplanar ellipses
(Universitat Politècnica de Catalunya, 2014-10)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThis work solves the problem of computing the relative position of two affine coplanar ellipses in terms of the coefficients that deffine their equations without solving the quartic equation for the intersection points. ... -
Proper generalized decomposition solutions within a domain decomposition strategy
(John Wiley & sons, 2018-03-30)
Article
Accés obertDomain Decomposition strategies and the Proper Generalized Decomposition are efficiently combined to obtain a fast evaluation of the solution approximation in parameterized elliptic problems with complex geometries. The ...
