“…We denote this space by (R 3 , , ). In a similar case, Beneki, Kaimakamis and Papantoniou [2], studied helicoidal surfaces with prescribed Gaussian and mean curvature in Minkowski space R In the recent work [4], Corro, Pina and Souza, began to study the surface theory for a three-dimensional complete manifold (R 3 , , g ), where , g is a conformal metric to Euclidean metric , , which means that there exists a positive differentiable function F : R 3 → R such that…”
