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…
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…
Timelike Surfaces with Parallel Normalized Mean Curvature Vector Field in the Minkowski 4-Space
Victoria Bencheva, Velichka Milousheva
In the present paper, we study timelike surfaces with parallel normalized mean curvature vector field in the four-dimensional Minkowski space. We introduce special isotropic parame…
