Maximal surfaces with conelike singularities
Maximal surfaces with conelike singularities
A spacelike surface in the 3-dimensional Minkowski space $L^{3}=(R^{3},$ $dx^{2}+dy^{2}$ $-dz^{2})$ is said to be maximal if the mean curvature vanishes identically.Any spacelike surface in $L^{3}$ can be represented locally as the graph $\{z=u(x, y)\}$ of
