Abstract :In this work we study vertical graph surfaces invariant by parabolic screw motions with pitch $\\ell >0$ and constant Gaussian curvature or constant extrinsic curvature in the product space $\\mathbb H^2 \\times \\mathbb R$. In particular, we determine flat and extrinsically flat graph surfaces in $\\mathbb H^2 \\times \\mathbb R$. We also obtain complete and non-complete vertical graph surfaces in $\\mathbb H^2 \\times \\mathbb R$ with negative constant Gaussian curvature and zero extrinsic curvature.
Keywords : Parabolic screw motion, extrinsic curvature
