Bending the Helicoid [PDF]

open access: yes, 2020
We construct Colding-Minicozzi limit minimal laminations in open domains in R 3 with the singular set of C 1 -convergence being any properly embedded C 1,1 -curve.

Higher Genus Doubly Periodic Minimal Surfaces [PDF]

open access: yes, 2018
We construct Weierstrass data for higher genus embedded doubly periodic minimal surfaces and present numerical evidence that the associated period problem can be solved.

On constant higher order mean curvature hypersurfaces in Hn×R ${\mathbb{H}}^{n}{\times}\mathbb{R}$

open access: yesAdvanced Nonlinear Studies
We classify hypersurfaces with rotational symmetry and positive constant r-th mean curvature in Hn×R ${\mathbb{H}}^{n}{\times}\mathbb{R}$ . Specific constant higher order mean curvature hypersurfaces invariant under hyperbolic translation are also ...

Compact hypersurfaces in a locally symmetric manifold [PDF]

open access: yes, 2016
Let M be an n-dimensional compact hypersurface in a locally symmetric manifold Nn+1. Denote by S and H the squared norm of the second fundamental form and the mean curvature of M.

Disc stackings and their Morse index

open access: yesAdvanced Nonlinear Studies
We construct free boundary minimal disc stackings, with any number of strata, in the three-dimensional Euclidean unit ball, and prove uniform, linear lower and upper bounds on the Morse index of all such surfaces. Among other things, our work implies for

Type I+ Helicoidal Surfaces with Prescribed Weighted Mean or Gaussian Curvature in Minkowski Space with Density

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
In this paper, we construct a helicoidal surface of type I+ with prescribed weighted mean curvature and Gaussian curvature in the Minkowski 3−space ℝ13${\Bbb R}_1^3$with a positive density function. We get a result for minimal case.

Embedded Minimal Ends of Finite Type

open access: yes, 1999
.-We prove that the end of a complete embedded minimal surface in R 3 with infinite total curvature and finite type has an explicit Weierstrass representation that only depends on a holomorphic function that vanishes at the puncture.

Cartan Forms for First Order Constrained Variational Problems [PDF]

open access: yes, 2020
Given a constrained variational problem on the 1-jet extension J 1 Y of a fibre bundle p : Y → X, under certain conditions on the constraint submanifold S ⊂ J 1 Y , we characterize the space of admissible infinitesimal variations of an admissible section

Survey on real forms of the complex A2(2)-Toda equation and surface theory

open access: yesComplex Manifolds, 2019
The classical result of describing harmonic maps from surfaces into symmetric spaces of reductive Lie groups [9] states that the Maurer-Cartan form with an additional parameter, the so-called loop parameter, is integrable for all values of the loop ...

An eigenvalue estimate for self-shrinkers in a Ricci shrinker

open access: yesAdvanced Nonlinear Studies
In this paper, we study the drifted Laplacian Δf on a hypersurface M in a Ricci shrinker (M̄,g,f) $\left(\bar{M},g,f\right)$ . We prove that the spectrum of Δf is discrete for immersed hypersurfaces with bounded weighted mean curvature in a Ricci ...
