具有有限个奇点的degenerateMonge-Ampere方程的整体解

Entire solutions of the degenerateMonge-Ampere equation with a finite number of singularities

Jose' Antonio Galvez, Barbara Nelli

摘要:

我们确定了二维退化Monge-Ampere方程u_{xx} u_{yy} - u_{xy} ^2=0在穿孔平面上的所有C^2-解的整体行为.有了这个,我们在一次或两次穿孔平面中对每个解进行分类。此外,当我们有两个以上的奇点时,如果解u在半带中不是线性的,我们得到奇点被放置在凸多面体P的顶点处,并且u的图是由P外部的圆锥片构成的,这些圆锥片沿着多面体的边适当地胶合。最后,如果我们寻找分析解,那么最多有一个奇点,并且$u$的图要么是圆柱(没有奇点),要么是圆锥(有一个奇点)。

英文摘要:

We determine the global behavior of every C^2-solution to the two-dimensional degenerate Monge-Ampere equation, u_{xx}u_{yy}-u_{xy}^2=0, over the finitely punctured plane. With this, we classify every solution in the once or twice punctured plane. Moreover, when we have more than two singularities, if the solution u is not linear in a half-strip, we obtain that the singularities are placed at the vertices of a convex polyhedron P and the graph of u is made by pieces of cones outside of P which are suitably glued along the sides of the polyhedron. Finally, if we look for analytic solutions, then there is at most one singularity and the graph of $u$ is either a cylinder (no singularity) or a cone (one singularity).
