Un théorème d'unicité de l'hélicoïde

Eric Toubiana (1988)

Annales de l'institut Fourier

Nous montrons qu’une surface minimale complété, plongée dans R 3 / Z , de courbure totale finie et homéomorphe a S 2 moins deux points est l’hélicoïde.

Unduloids and their geometry

Mariana Hadzhilazova, Ivaïlo M. Mladenov, John Oprea (2007)

Archivum Mathematicum

In this paper we consider non-compact cylinder-like surfaces called unduloids and study some aspects of their geometry. In particular, making use of a Kenmotsu-type representation of these surfaces, we derive explicit formulas for the lengths and areas of arbitrary segments, along with a formula for the volumes enclosed by them.

Universal spaces for manifolds equipped with an integral closed k -form

Hông-Vân Lê (2007)

Archivum Mathematicum

In this note we prove that any integral closed k -form φ k , k 3 , on a m-dimensional manifold M m , m k , is the restriction of a universal closed k -form h k on a universal manifold U d ( m , k ) as a result of an embedding of M m to U d ( m , k ) .
