In this paper, we study surfaces in Lorentzian product spaces M^ 2 (c) * R _1. We classify
constant angle spacelike and timelike surfaces in S^ 2 * R _1 and H^ 2 * R _1. Moreover …

In this study, constant angle ruled surfaces with a pointwise 1-type Gauss map, which is very
useful in the classification of surfaces, are investigated in terms of the Frenet elements of the …

Let N be a Lorentz surface and let∂ t be a unit vector field on the Lorentz manifold N× R
tangent to R. A timelike surface Σ in N× R is said to have a canonical null direction with …

In this study, for the first time, a method is given for a developable ruled surface to be a
constant angle ruled surface. The general equations of constant angle surfaces have been …

We study constant angle semi-Riemannian hypersurfaces M immersed in semi-Riemannian
space forms, where the constant angle is defined in terms of a closed and conformal vector …

ABSTRACT A constant angle surface in Minkowski space is a spacelike or timelike surface
whose unit normal vector field makes a constant (hyperbolic) angle with a fixed vector. In this …

A helix surface or constant angle surface is a surface whose unit normal vector field forms a
constant angle with a fixed field of directions of the ambient space. In this paper we study …

In the present paper, we discuss the singular minimal surfaces in a Euclidean 3-space R^{3}
which are minimal. In fact, such a surface is nothing but a plane, a trivial outcome. However …
