Polynomial Weingarten surfaces of tubular type
Silva, Fernando Gasparotto da
MetadataShow full item record
This work seeks to contribute to the classification of Weingarten surfaces. More precisely, it fully classifies three families of surfaces (named tubular, cyclic and canal surfaces) in a tridimensional space form (Euclidean, Lorentzian and Hyperbolic spaces) that verify an arbitrary polynomial relation among its Gaussian and mean curvatures. The results obtained provide geometric features of the surface as well as algebraic conditions over the polynomial that defines a surface as Weingarten. Furthermore, results that allow us to investigate Weingarten surfaces only by the polynomial analysis are presented.

Superfícies de Curvatura Média Constante no Espaço Euclidiano Santos, José Ramos Araujo dos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, Câmpus São Carlos, 19/03/2019)This paper deals with the surfaces of constant mean curvature in the Euclidean space. The first part of the text is devoted to minimal surfaces. We begin our studies with the Enneper-Weirstrass Representation Theorem and ...
A Equação de Codazzi em superfícies Santos, Maria Rosilene Barroso dos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, , 04/03/2011)In this work, based on the article The Codazzi Equation for Surfaces by Juan A. Aledo, José M. Espinar and José A. Gálvez , we describe some applications of an abstract theory for the Codazzi equation on surfaces. ...
Pseudo-parallel immersions in SnxR and HnxR, and constant anisotropic mean curvature surfaces in R3 Tassi, Marcos Paulo (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, Câmpus São Carlos, 20/12/2019)In this Ph.D. thesis, we investigate two topics in Differential Geometry. The first topic refers to the study of pseudo-parallel submanifolds in the ambient spaces SnxR and HnxR. We complete the partial classification given ...
