TY - JOUR AU - Yoon, Dae Won PY - 2006/09/30 Y2 - 2024/03/29 TI - On the second Gaussian curvature of ruled surfaces in Euclidean $3$-space JF - Tamkang Journal of Mathematics JA - Tamkang J. Math. VL - 37 IS - 3 SE - Papers DO - 10.5556/j.tkjm.37.2006.167 UR - https://journals.math.tku.edu.tw/index.php/TKJM/article/view/167 SP - 221-226 AB - In this paper, we mainly investigate non developable ruled surface in a 3-dimensional Euclidean space satisfying the equation $K_{II} = KH$ along each ruling, where $K$ is the Gaussian curvature, $H$ is the mean curvature and $K_{II}$ is the second Gaussian curvature.
