Sinica-NCTS Geometry Seminar 主講者: Professor Jaewon Lee (Yeungnam University, Korea) 講題: Helicoidal Surfaces with prescribed curvatures in $Nil_3$ 時間: 2014-07-18 (Fri.)  16:00 - 17:00 地點: 數學所 714 研討室 (台大院區) Abstract: We study helicoidal surfaces in the 3-dimensional Heisenberg group $Nil_3$. Also, we construct helicoidal surfaces in $Nil_3$ with prescribed Gaussian curvature or mean curvature given by smooth functions. As the results, we classify helicoidal surfaces with constant Gaussian curvature or constant mean curvature. || Close window ||
