Parallel Surfaces of Spacelike Ruled Weingarten Surfaces in

Parallel Surfaces of Spacelike Ruled Weingarten Surfaces in Minkowski 3-space

In this work, it is shown that parallel surfaces of spacelike ruled surfaces which are developable are spacelike ruled Weingarten surfaces. It is also shown that parallel surfaces of non-developable ruled Weingarten surfaces are again Weingarten surfaces. Finally, some properties of that kind parallel surfaces are obtained in Minkowski 3-space
