对于α-相对超曲面上的一般体积变分问题,得到其Euler-Lagrange方程是一个四阶偏微分方程,进而通过解这个四阶方程的一类边界问题可以构造许多欧式完备α-相对超曲面.
A general volume variational problem for α-relative hypersurfaces is considered, and it is proved that its Euler-Lagrange equation is a four order PDE. By solving some boundary problem of this PDE, we can construct many Euclidean complete a-relative hypersurfaces.
