In this article, a new type of ruled surfaces in a Lorentz 3-space R 3 1 is obtained by a strictly connected time-like oriented line moving with FrenetÕs frame along a space-like curve. These surfaces are classified into time-like and space-like surfaces. The well-known theorems due to Bonnet and Chasles in the 3-dimensional Euclidean space are proved for a(More)
