Simply-connected Nonpositive Curved Surfaces in R3
where |B| is the length of second fundamental form. |B|2 = 4|H|2 − 2K, where H is the mean curvature and K is the Gauss curvature. The curvature of minimal surfaces is nonpositive. Then we exam what is still hold for some minimal surface theorems if extending the minimal condition H ≡ 0 to the surfaces with K ≤ 0 and (1). In 2001, F. Xavier [18] has the following theorem: Theorem [Xavier]. Let ...
متن کاملSmooth Surfaces with Non-simply-connected Complements
We give two constructions of surfaces in simply-connected 4-manifolds with non simply-connected complements. One is an iteration of the twisted rim surgery introduced by the first author [7]. We also construct, for any group G satisfying some simple conditions, a simply-connected symplectic manifold containing a symplectic surface whose complement has fundamental group G. In each case, we produ...
متن کاملOn edge tricolorations of triangulations of simply connected surfaces
This paper studies the tricolorations of edges of triangulations of simply connected orientable surfaces such that the degree of each interior vertex is even. Using previous results on lozenge tilings, we give a linear algorithm of coloration for triangulations of the sphere, or of planar regions with the constraint that the boundary is monochromatic. We define a flip as a shift of colors on a ...
متن کاملFast Disk Conformal Parameterization of Simply-connected Open Surfaces
Surface parameterizations have been widely used in computer graphics and geometry processing. In particular, as simply-connected open surfaces are conformally equivalent to the unit disk, it is desirable to compute the disk conformal parameterizations of the surfaces. In this paper, we propose a novel algorithm for the conformal parameterization of a simply-connected open surface onto the unit ...
متن کاملDensity-equalizing maps for simply-connected open surfaces
In this paper, we are concerned with the problem of creating flattening maps of simplyconnected open surfaces in R3. Using a natural principle of density diffusion in physics, we propose an effective algorithm for computing density-equalizing flattening maps with any prescribed density distribution. By varying the initial density distribution, a large variety of mappings with different properti...
