Helicoidal hypersurfaces of dini-type in the four dimensional minkowski space
Abstract
We define Ulisse Dini-type helicoidal hypersurfaces with spacelikeaxis in Minkowski 4-spaceE41. We compute the Gaussian and the mean curva-ture of the hypersurface. Moreover, we obtain some special symmetries to thecurvatures when they are flat and maximal.
