在几何上,极小曲面是一个具有平均曲率=0的曲面。 这包括, 但不被限制对, 有最小的面积而依于边界上的限制的曲面。 极小曲面的例子包括平面、球面、懸鏈曲面、螺旋面、Enneper曲面、等等。 为了创造物质的模范,可以把线框浸洗浸洗而形成肥皂泡。 一些非中文的文字因为尚未翻譯而被隐藏,歡迎參與翻譯。
A minimal surface made by rotating a catenary once around the axis is called a catenoid. A surface swept out by a line rotating with uniform velocity around an axis perpendicular to the line and simultaneously moving along the axis with uniform velocity is called a helicoid. Recent work in minimal surfaces has identified new completely embedded minimal surfaces, that is minimal surfaces which do not intersect. In particular Costa's minimal surface was first described mathematically in 1982 by Celso Costa and later visualized by Jim Hoffman. This was the first such surface to be discovered in over a hundred years. Jim Hoffman, David Hoffman and William Meeks III, then extended the definition to produce a family of surfaces with different rotational symmetries. Minimal surfaces have become an area of intense mathematical and scientific study over the past 15 years, specifically in the areas of molecular engineering and materials science, due to their anticipated nanotechnology applications. The definition of minimal surfaces can be extended to cover constant mean curvature surfaces. These surfaces are sometimes called "noid". [编辑] See also[编辑] References
