Timelike meridian surfaces of hyperbolic type in the Minkowski 4-space
Victoria Bencheva, Velichka Milousheva
We consider a special class of timelike surfaces in the four-dimensional Minkowski space which are one-parameter systems of meridians of rotational hypersurfaces with spacelike axi…
Canonical parameters on marginally trapped surfaces in the Minkowski 4-space
Miroslav Maksimović, Velichka Milousheva
Marginally trapped surfaces are spacelike surfaces in the Minkowski space whose mean curvature vector is lightlike at each point. In general, the marginally trapped surfaces are de…
Canonical parameters on a surface in
Ognian Kassabov, Velichka Milousheva
In the present paper, we study surfaces in the four-dimensional Euclidean space . We define special principal parameters, which we call canonical, on each surface wit…
Timelike Meridian Surfaces of Elliptic type in the Minkowski 4-Space
Victoria Bencheva, Velichka Milousheva
We consider a special family of 2-dimensional timelike surfaces in the Minkowski 4-space which lie on rotational hypersurfaces with timelike axis and call them mer…
Fundamental Theorems for Timelike Surfaces in the Minkowski 4-Space
Victoria Bencheva, Velichka Milousheva
In the present paper, we study timelike surfaces free of minimal points in the four-dimensional Minkowski space. For each such surface we introduce a geometrically determined pseud…
Relation between the minimal Lorentz surfaces in and
Krasimir Kanchev, Ognian Kassabov, Velichka Milousheva
In this paper we give Weierstrass-type representation formulas for the null curves and for the minimal Lorentz surfaces in the Minkowski 3-space using real-valued f…
