Choe and Soret [1] constructed infinitely many compact embedded minimal surfaces in S 3 by desingularizing Clifford tori which meet each other along a great circle at the angle of the same size. We show their method works with some modifications to c

We show that any ruled minimal surface in the Berger sphere is a helicoid whose axis is a Hopf fiber by solving the ruled minimal surface equation in the parametric form.

It is shown that parts of planes, helicoids and hyperbolic paraboloids are the only minimal surfaces ruled by geodesics in the three dimensional Riemannian Heisenberg group. It is also shown that they are the only surfaces in the three dimensional He

It is well known that space-like maximal surfaces and time-like minimal surfaces in Lorentz–Minkowski 3-space L 3 have singularities (i.e. points where the induced metric degenerates) in general. We are interested in the case where the singular set

It is shown that a minimal surface in ℍ2×ℝ is invariant under a one-parameter group of screw motions if and only if it lies in the associate family of helicoids. It is also shown that the conjugate surfaces of the parabolic and hyperbolic helico

We provide two characterizations of helicoids in S 2 x ℝ and in ℍ 2 x ℝ. First, we show that any nontrivial ruled minimal surface in S 2 x ℝ and in ℍ 2 × ℝ is a part of a helicoid. Second, we also show that these surfaces can be characte
