Linear Weingarten Helicoidal Surfaces in Isotropic Space

Introduced in 1861 [1], a Weingarten surface in the Euclidean three-dimensional space E3 is a surface M, whose mean curvature H and Gaussian curvature K satisfy a non-trivial relation Φ(H, K) = 0. Such a surface was introduced by Weingarten. The class of Weingarten surfaces is remarkably large, and it consists of intriguing surfaces in the Euclidean space: the constant mean curvature surfaces, the constant Gaussian curvature surfaces and all rotational surfaces. As a special case of Weingarten surfaces, we consider that the Weingarten relation Φ is linear in its variables. That is, Φ satisfies the following relation
