  • As a suitable application of the well known generalized maximum principle of Omori-Yau, we obtain rigidity results concerning to a complete hypersurface immersed with bounded mean curvature in the $(n+1)$-dimensional hyperbolic space $\mathbb{H}^{n+1}$. In our approach, we explore the existence of a natural duality between $\mathbb{H}^{n+1}$ and the half $\mathcal{H}^{n+1}$ of the de Sitter space $\mathbb{S}_1^{n+1}$, which models the so-called steady state space.

  • We construct generalized Cauchy-Riemann equations of the first order for a pair of two ℝ-valued functions to deform a minimal graph in ℝ3 to the one parameter family of the two dimensional minimal graphs in ℝ4. We construct the two parameter family of minimal graphs in ℝ4, which include catenoids, helicoids, planes in ℝ3, and complex logarithmic graphs in ℂ2. We present higher codimensional generalizations of Scherk's periodic minimal surfaces.
