Classificação de cônicas e quádricas
(Universidade Estadual Paulista (Unesp), 2015-02-25)
The main objective of this study is to classify the conics curves and the quadrics surfaces that are represented through equations Ax2 + By2 + Cz2 + Dxy + Exz + Fyz + Gx + Hy + Iz + J = 0 whit A,B,C,D,E.F,G,H, I, J 2 R. ...
About The Semiample Cone Of The Symmetric Product Of A Curve
(2017)
Let C be a smooth curve which is complete intersection of a quadric and a degree k > 2 surface in P-3 and let C-(2) be its second symmetric power. In this paper we study the finite generation of the extended canonical ring ...
Complexo quadrático de retas
(Universidade Federal de Minas GeraisUFMG, 2007-04-16)
On studying the Grassmanian of lines in projective space and Plücker's Quadric related to it, we noted the presence of interesting congurations of lines. From those congurations, a surface in projective space, the so called ...

PL-Geodesics on PL-continuous partial meshes
(2001)
Geometric characteristics of 2-manifolds embedded in R3 space have been analyzed from the point of view of differential geometry and topology -- In the past, results relevant to these areas have been found for C∞ curves ...

Determinação de comportamento não caótico de sistemas diferenciais quadráticos em R^3 via superfícies algébricas invariantes
(Universidade Estadual Paulista (Unesp), 2019-04-25)
Neste trabalho, apresentamos uma condição algébrica suficiente para determinar o comportamento não caótico de sistemas diferenciais polinomiais definidos em R^3. Usando essa condição, apresentamos um resultado parcial para ...
Digital Technology in Higher Education: Identification of Surfaces in Space Generated by Functions of Two Variables
(SpringerDE, 2023)
This forms part of a research project to characterize the mathematical work performed by higher education students in developing a didactic sequence, through digital technology, in which they mobilize the concept of surfaces ...
