Повний текст джерелаWe study the quantity denoted Kvol defined by KVol(X,g) = Vol(X,g)*sup_{alpha,beta} frac{Int(alpha,beta)}{l_g (alpha)l_g(beta)} where X is a compact surface of genus s, Vol(X,g) is the volume (area) of the surface with respect to the metric g and alpha, beta two simple closed curves on the surface X.The main results of this thesis can be found in Chapters 3 and 4. In Chapter 3 titled "Algebraic intersection for translation surfaces in the stratum H(2)" we are interested in the sequence of kvol of surfaces L(n,n) and we provide that KVol(L(n,n)) goes to 2 when n goes to infinity. In Chapter 4 titled "Algebraic intersection for translation surfaces in a family of Teichmüller disks" we are interested in the Kvol for a surfaces belonging to the stratum H(2s-2) wich is an n-fold ramified cover of a flat torus. We are also interested in the surfaces St(2s-1) and we show that kvol(St(2s-1))=2s-1. We are also interested in the minimum of Kvol on the Teichmüller disk of the surface St(2s-1) which will be (2s-1)sqrt {frac {143}{ 144}} and it is achieved at the two points (pm frac{9}{14}, frac{sqrt{143}}{14})

Повний текст джерелаThis thesis is divided in two main parts. First, we study the relationships between intersection theories in tropical and algebraic geometry. Then, we study the question of the possibilities for the distribution of the real inflection points associated to a real linear system defined on a smooth real algebraic curve. In the first part, we present new results linking algebraic and tropical intersection theories over a very-affine algebraic variety defined over a particular non-Archimedean field (known as Mal’cev-Newmann field). The main result concerns the intersection of a one-dimensional algebraic cycle with a Cartier divisor in a variety with simple tropicalization. In the second part, we obtain first a characterization of the distribution of real inflection points associated to a real complete linear system of degree d>1 defined over a smooth real elliptic curve. Then we study some canonical, non-hyperelliptic real algebraic curves of genus 4 in a 3-dimensional projective space. We obtain a formule that relies the amount of real Weierstrass points of such a curve with the Euler-Poincaré characteristic of certain topological space. Finally, using O. Viro’s Patch-working technique, we construct an example of a smooth, non-hyperelliptic real algebraic curve of genus 4 having 30 real Weierstrass points

Повний текст джерелаLa première partie de cette thèse porte sur l'utilisation de méthodes algébriques en modélisation géométrique, l'accent étant mis sur la topologie, l'intersection et l'auto-intersection dans le cadre du calcul d'arrangement d'ensembles semi-algébriques comme les courbes et surfaces à représentation implicite ou paramétrique. Une attention particulière est portée à la généricité des algorithmes qui peuvent être spécifiés quel que soit le contexte, puis spécialisés pour répondre aux exigences d'une certaine représentation.
La seconde partie de cette thèse présente le prototypage d'un environnement de modélisation géométrique dont le but est de fournir un moyen générique et efficace pour modéliser des solides à partir d'objets géométriques à re\-pré\-sen\-ta\-tion algébrique tels que les courbes et surfaces implicites ou paramétriques, à la fois d'un point de vue utilisateur et d'un point de vue de développeur, par l'utilisation de librairies de calcul symbolique numérique pour la
manipulation des polynômes définissant les objets géométriques.

Повний текст джерелаReal algebraic geometry is in its simplest definition, the study of sets of solutions of a system of polynomial equations with real coefficients. In this theme, we focus on the intersections of quadrics where already the case of three quadrics remains wide open. Our subject can be summarized as the topological study of real algebraic varieties and interaction between their topology on the one hand and their deformations and degenerations on the other hand, a problem coming from the 16th Hilbert problem and enriched by recent developments. In this thesis, we will focus on maximum intersections of real quadrics and particularly prove the existence of such intersections using research developments made since the late 80. In the case of intersections of three quadrics, we will point the very close link between the intersections on the one hand and on the other plane curves, and show that the study of M-curves (one of the problems of the 16th Hilbert problem) may be done through the study of maximum intersections. Next, we will use the study on nodal plane curves to determine in some cases deformation classes of intersections of three real quadrics
