Approximating Convex Shapes With Respect to Symmetric Difference Under Homotheties.

, 2016
The symmetric difference is a robust operator for measuring the error of approximating one shape by another. Given two convex shapes P and C, we study the problem of minimizing the volume of their symmetric difference under all possible scalings and translations of C. We prove that the problem can be solved by convex programming.

Design and implementation of a task sequence for teaching homothety

Eurasia Journal of Mathematics, Science and Technology Education
The teaching of geometry in Chile faces several challenges, as evidenced by the low performance of students in international assessments. In particular, the concept of homothety is impacted by teaching methodologies that emphasize rote memorization and procedural repetition rather than conceptual understanding.

Isogeny character and uniform bound for homotheties

, 2008
L'objet de cette thèse est l'obtention de résultats uniformes sur l'image des représentations galoisiennes associées aux points de torsion des courbes elliptiques possédant une isogénie de degré premier. Le cadre se compose d'un corps de nombres K différent de Q et galoisien sur Q, d'une courbe elliptique E définie sur K et d'un nombre premier p ; on ...
