We study 3-manifolds in $\mathbb{R}^5$ with corank $1$ singularities. At the singular point we define the curvature locus using the first and second fundamental forms, which contains all the local second order geometrical information about the manifo

Submanifolds in Lorentz-Minkowski space are investigated from various mathematical viewpoints and are of interest also in relativity theory. We define the hyperbolic surface and the de Sitter surface of a curve in the spacelike hypersurface M in the

Nesta tese, investigamos a geometria de curvas no 3-espaço e no 4-espaço de Minkowski usando a teoria de singularidades, mais especificamente, a teoria de contato. Para isto, estudamos as famílias de funções altura e de funções distância ao q

We study the geometry of curves in the Minkowski space and in the de Sitter space, specially at points where the tangent direction is lightlike (i.e. has length zero) called lightlike points of the curve. We define the focal sets of these curves and

In mathematical physics, Minkowski space (or Minkowski space-time) is a combination of three-dimensional Euclidean space and time into a four-dimensional manifold. The hyperbolic surface and de Sitter surface of a curve are defined in the spacelike h
